The door in question was fitted upside down and used a D pull plate fitted to the inside with a surface barrel bolt used as the interior lock mechanism.
You can see in the first picture, the exterior door side with the old plates removed, revealed large coach-bolt holes where the old plates were fitted.
The inside D pull had been broken off and exposed bolts looked unsightly. They were using a packing box strap to pull the door open, but inspection by the local authority having jurisdiction (AHJ), required a properly operating door handle to be installed.
We removed the damaged plates which revealed the poor workmanship from the previous installer.
You can see that we used 4" x 20" push plates and over lapped the bottom plate and top plate.
The cross bore hole was in the wrong position, because the door was fitted upside down.
The cover plates easily covered most of the damage, effectively improving the aesthetics, expertly. A clean look is a professional look.
We were required to drill a 40mm (1-3/4") cross bore hole in the cover plates to accept the new lock. These plates are stainless steel and our hole saws were not sharp enough to easily complete the desired holes. As a consequence, we were required to lace-drill the holes in the plates.
Lace-drilling is a term coined by professional metalworkers to explain a method of making a larger hole in an application, when a larger drill bit or hole saw would not work easily. The installer will drill a series of smaller holes in the application and cut the material out to make the hole desired, larger.
Because the door frame was a commercial steel frame, the existing strike plate was located in a different position to the existing cross-bore hole in the existing upside-down door.
We were required to accurately allign the new lock with the existing strike plate and drill new cross-bore holes accordingly.
You can see the finished look is very professional. The new lock operates flawlessly.
The door is a high trafficked door with sometimes hundreds of daily uses, hence the decision to use high-quality hardware.
