Step by Step:
Peel narrow backing paper strip from the installation guide's "LOCKSCREWS" side. Position guide as shown and use punch to mark striking plate hole location (2 arrows). Now peel backing paper from foam tape (small arrow).
Close door firmly on foam tape. This will transfer guide to exact location on inside of door (or drawer). Open door, hold guide down, and mark 4 screw locations for lock installation (4 arrows).
Measure door thickness, then subtract 3/16". Position drill depth gauge on bit and move it the required distance from the tip so the hole drilled will be within 3/16" of cabinet door front. Drill into "7MM HOLE" location on guide. Use CAUTION and DO NOT DRILL THROUGH DOOR. It is important that the hole you drill is within 3/16" of the front of the door. Hole must also be clean and free of debris.
Match striking plate over 2 locations marked during Step 1. Use screws and install loosely so slot adjustment can be made later. Match TOT-LOK Assembly into 7mm holes (install Plunger/Slug if necessary), align over 4 marks (from Step 2) and screw in place with four 1/2" screws. A pair of auxiliary holes are provided for variations in door panels. Assure proper function prior to closing. Note proper position of striking plate and screw it down tight.
