Pro-Lok EAP-110-C – Frequently Asked Questions
1) Can I use a Pro-Lok bore adapter plate to fix an oversized 2-1/8 inch hole in a door?
That is what the Pro-Lok 2-3/4 inch bore adapter plate is for. It reduces a 2-1/8 inch bore down to 1-1/2 inch, so a door that was drilled for a standard cylindrical lock prep can take a smaller cylinder without replacing the door. The steel plate also covers wood damage around the bore and adds reinforcement at the lock.
2) Which cylinders will fit a 1-1/2 inch reduced bore adapter plate?
The Pro-Lok adapter plate is made for mortise, deadbolt and rim cylinders, which is why it steps the opening down to 1-1/2 inch. If you are mounting a rim cylinder on a door that was previously bored for a knob or lever set, this is the plate that closes that gap.
3) Does the Pro-Lok adapter plate come as one piece or do I need two for a through-door install?
Two parts ship together in the kit, so you get a plate for each face of the door on a through-bore application. You do not need to order a second one to finish both sides.
4) Is the Pro-Lok bore adapter plate strong enough for a commercial entry door?
It is a steel plate rated as a commercial item, and reinforcing the locking area is one of its stated purposes alongside covering damage and resizing the bore. For property managers dealing with a kicked or pried tenant door, it lets you salvage the existing leaf rather than hang a new one.
5) Will a 2-3/4 inch adapter plate cover a chewed-up or splintered bore on a wood door?
Yes. At 2-3/4 inches the plate is wider than the 2-1/8 inch bore it covers, so the extra material laps over the damaged wood around the hole. It is a common repair on wood doors where the old lock tore out.
