Pro-Lok Installation Templates were created by industry professionals to provide the easiest, fastest, most accurate and mistake-proof way to drill the proper holes for door locking hardware. The installation templates precisely guide the cutter along fixed cutting patterns that are accurately shaped and sized in order to produce the exact holes needed for the type of lock hardware you are installing. You will get exacting accuracy and finished work in the same time it takes others just to set up. Simply cut along the patterns and your results are guaranteed. With our installation templates you can be certain that each hole you cut will be right the first time, consistently the same every time, and that the lock hardware you are installing will always fit and install with ease. The installation templates work equally well for all retrofit, remodeling, and new installation applications. The installation templates work with our INCL Universal Clamp. The Universal Installation Template Clamp lets you use more than 40 templates for your most standard door lock installations.
