Extra-Strong Security Blocker Plate And Concealed Continuous Hinge Installed To Very High Traffic Shopfront Door

 Very early today, we installed a custom built mild steel security blocker plate and concealed fix continuous hinge to a very high-traffic convenience store, to upgrade and improve the operation of the relatively newly installed aluminum shopfront door.

Our loyal returning customer, who has used us consistently for the last 5 years, a user of our Extreme Security Bilock Restricted Key Control System for multiple properties, owns this convenience store on a busy main arterial road in the North County of St Louis.

The area is experiencing a gradual rebirth, especially since the recent issues with nearby Ferguson Missouri, a site that was in the national and international news a few years ago due to the unfortunate shooting of an unarmed African-American teenager by a police officer.

The incident sparked riots and protests unseen in the St Louis region for a great many years.

We were required to custom design and install mild steel blocker plates with sex bolts. There was a 3/16" clearance difference between the operating door and the fixed leaf
door. We had to remove the existing security bars, cut them down in length to enable the concealed continuous hinge to fit correctly (not pictured).

 Installing the custom designed mild steel long blocker plates, required a 3" wide x 1/8" thick inside plate, combined with another 4" wide x 1/8" thick outside plate to be installed to the external of the operating door, so that the plate would conceal access to the latch mechanism and cover the fixed leaf edge (which was sitting 3/16" out from the operating leaf when closed)

Installing sex bolts (also known as concealed bolts) is the obvious solution to providing top security for externally mounted product because they prevent would be burglars from using conventional tools to remove the bolts.

Drilling through 2 separate mild steel plates, that were deliberately separate and not conjoined, providing a minimal gap between the plates increases the security application due to the laminating effect.

Laminating is a term used when there is a slight separation between panels. The effect of laminating, naturally increase the strength of the product (depending on the laminate material).

You can see the inside screw under the internal security bar in this image. We installed a number of these sex bolts to the application to increase the security across multiple points, providing significantly greater strength to the application.

The customer, had new doors installed only 2 months previously by a shop fitting company. Unfortunately the installer decided to use only 2 regular butt hinges on this extremely high-trafficked door. The door is operated between 10,000 and 20,000 times daily.

The extreme use and operation of these doors by customers, meant that the 2 4" butt hinges were not up to the job requirement for continued longevity and efficient operation. In 2 months, the door was already beginning to sag, to the point where the owner required to pay an employee overtime to maintain a continued presence on site, because the doors would not secure correctly.

We have not provided an external image of the concealed continuous hinge, but it is fitted with more sex bolts securing it permanently in place.

The concealed continuous hinge is manufactured by Select Hinges, a company that produces there products in America and are designed to last 50 years and that is their warranty period too.

With correct installation these doors will not sag, due to the number of fastener points, increasing the strength of the fitting.

We have installed a significant number of continuous hinges in recent years, mostly to shopfront doors due to the standard pivots wearing quite quickly and customers having many issues relating to sagging doors, inability to secure properly and causing angst for staff.

We were required to modify the security bars on this door to enable the continuous hinge to install correctly.

The entire project was required to be completed before the late Sunday opening time, because it is the only day of the week, where traffic is quietest before 9 am. We arrived at 6 am and began the project at 6.30am. Total completion in 5 hours. Certainly a mean feat in extreme heat conditions (but before the main heat of the day).

We will return at another time to upgrade the door locks at this property to the customers Bilock Extreme Security Restricted Key Control system. Then they will enjoy 100% bump proof and virtually pick proof lock cylinders with virtually impossible to duplicate color coded restricted keys, that will increase the security while protecting the owner from would be surreptitious attempts to copy keys.

Came to the rescue and did what was needed. Pointed out problems but assured not urgent. Please feel free to have Danny pass out my number for my total experience review 314-351-5553

Charlie M. (St Louis, MO) November 2015

Danny was pleasure to meet and was very knowledgable. He explained several lock replacement options but I decided none of them were a good fit for a storm door, however, I did replace a lock on my entry door with a type of lock I had never seen before. I would highly recommend this company.
Patricia J (Bridgeton, MO) March 2014
They were prompt and showed up when he said he would show up. He knew his stuff. I had ordered new handles and he was honest enough to say that we don't need them that he can fix the doors and he did. Made me lock and unlock my doors to his satisfaction so that I knew what to do. Am very, very pleased with the service and cost.
Joyce K (Glencoe, MO) May 2015

Showed up on time for appointment. Was very knowledgeable about the project and offered a solution beyond what I asked to be done.
Stephen G (Chesterfield, MO) May 2015

Daniel was right on time, assessed the problems I had with two doors, made the repairs, and explained what caused the problems to begin with .... He is a "door expert" and a true professional. I highly recommend him.

Vince V (St. Louis MO) May, 2015

Danny was fabulous! He went over my concerns and he provided me with more than a fair quote. He was there when he said he was going to be there. I would highly recommend Danny. Cheers!
Denise S (Imperial, MO) May 18, 2014

Hired Danny to re-key locks on "new" house purchase. He advised to replace with new deadbolts & door knobs on 3 entry doors instead which I agreed with. All doors have 1 matching key & the safety of excellent quality product & workmanship. He also added new strike plate to door frame to complete project.. I recommend as your 1st & only call to a Locksmith.

Denise F (St. Louis, MO) April 3, 2014

Danny was very helpful in solving a pretty complex problem involving many lock.
Scott C (Eureka, MO) March 27, 2014

Needed patio door track to run smoothly. Arrived early, fixed door and explained what he was doing during repair. Quick and easy. Door works great, my wife will now speak to me, and I've become a better dancer.

Mike W. (Arnold/Oakville MO) July 2013

The owner spent a longtime with me on the phone helping diagnosis the problem. He was on-time, friendly and helped resolve my issue. I will definitely use him again!

Chris C (Lake St Louis, MO) July 2013

I had a very pleasant experience with Master Key Systems. They came out, did the job (which took longer than expected) and they did not change the price they quoted me. Now, I am not certain that it was a great value for the money because I don't have a comparison, but they did what they said, when they said, for the price they said. Enough said!!!

Antonio B (Saint Louis, Missouri) March 2013

Professional.. Upfront about charges. Fixed the sticky door within 20 minutes. I will recommend Master Key for exterior door issues.
Muthu R (Ballwin, MO) July 2012

Danny was a master craftsman, knowledgable and professional. I will be calling on him again in the future as well as passing on his services to friends and family.

Marsha L (Saint Louis, MO) July 2012

Danny was excellent! I called him on a Monday to fix a sliding glass door. He happened to have the exact part we needed (and it was not an easy find - we had looked everywhere) and he came over Tuesday evening. He stayed until 8:00 until the job was done, and cleaned up afterwards. He was courteous, professional, and efficient! I could not be happier!

Rachel P Maryland Heights, MO (July 2012)

He did an excellent job. Got there on time and quickly solved the issue. Was very pleasant and explained the situation and how to keep the door from sticking in the future. Would definitely use Master Key LLC again!

Neil F. (Saint Louis, MO) April 2012

Danny was very friendly and knowledgeable, although his apprentice seemed to do most of the work, Danny kept an eye on him to make sure it was done right. He had very reasonable pricing for re-keying.
Greg D (St Louis, MO) October 2011

He was extrememly fabulous and helpful and did a wonderful job. He was very professional.
Shannon M. (Arnold, MO) October 2011

Growing up spending so much of my time in Italy, the uniqueness of the Nova Classico left quite an impression on me. To be able to have and enjoy them in my own home here in the states is a nostalgic indulgence I'm enjoying beyond words. Thank you Danny for coordinating this transaction.

Joseph M (Chicago, IL) September 2011

great job. hired on the spot and he did job right then at great price

Ron B (Arnold, MO) July 2011

I searched the internet and found your services. I received three phone calls within several days. A service call was scheduled. Two gentlemen arrived promptly, analyzed the problem and fixed it.
James & Florenc M Saint Louis, MO July 2011

The repairman was on time and did an excellent job of fixing a very stubborn door lock. He was persistent and cleaned up the work area afterwards. I would use this service again.

Brenda F (Saint Peters, MO) June 2011

Danny at Master Key Systems has succeeded in making the purchasing of our Meroni door locks, from Italy, an absolute breeze. Even though I live in Australia with a 16hr time difference and was ordering door knobs from Italy that weren't in stock, the whole process was faultless. Danny was prompt and efficient with all his emails and made sure we had covered every possible variable so that the product I received was exactly as required. I would have no hesitation in recommending Danny for your next purchase.
Patrick Carr (Canberra, Australia)

Your product really helped because I needed to secure a nurse's station adjacent to a waiting room and needed a pocket door. Unfortunately, no real options were available to lock a pocket door effectively that would keep me compliant with HIPAA and secure an area that stores medical supplies. This was vitally important as this particular waiting room was for "waiting detox patients". Thank you very much.
Randall R The Fritz Clinic (Birmingham, Al) March 2011

Danny was very polite and knew what the problem was and how to fix it. He also gave me some information about other issues that could arise with my door and locks. Will hire again if I ever need that type of work done.
Jason M Imperial, MO March 2011

I had an exterior basement door that dragged when opening and closing. The hinges were not fitting properly and the door frame had shifted, probably due to the age of the house.The screwswould not go far enough into the wall without hitting stone...even using a special drill bit. Dan worked a long time drilling and sanding to shore up the door as best as possible. I know it will never be perfect. He could have easily sold me a new door and the same issue would happen. He was honest, thorough, and did an excellent job without charging me a fortune. I'm satisfied with the door now. If you want an honest, experienced man, Then Dan is the man

Roger M Saint Louis, MO March 2011

I purchased the Cowdroy P697 Pocket door lock with key over the internet. I emailed questions before my purchase and was provided with the answers quickly by return email. The purchase was quick and easy and the lock was shipped immediatly. Installation is quick and easy. But you do need to convert millimeters to inches (use the internet) in the installation instructions. And the lock looks great and works great. I will do business with them again. THANK YOU
