![]() Note: Always protect the surface of the cabinet door or drawer front to prevent any potential damage that could be caused by the installation jig. When the knob is loosened, the plate assemblies spread, reducing time required to remove and position the jig onto another cabinet or desk. Unlike the cylindrical lock jig, the cabinet jig plate assemblies are spring loaded. Like the cylindrical lock installation jig, the Bullseye Cabinet Lock Installation Jig has a plate leveling adjustment tool and an adjustment knob for tightening the unit flush onto a door or drawer front. To set the installation jig in proper position for the lock, there is a built-in vial level. To assist in the positioning process, the BUL-1 jig has a measuring gauge in the top of the right hand drill plate assembly ranging from 7/8” to three inches. Cabinet locks are positioned onto a door or drawer front at the backset necessary to accommodate the locking bolt or latch. Unlike door lock installation jigs, the A-1 Cabinet Lock Jig does not have stops to accommodate specific backsets. The jigs can accommodate cabinet door or drawer fronts from 7/16” to 1 ¼” thick. The 1 ¼” bushing is designed to accommodate 1 1/8 and 1 ¼ cam locks, including interchangeable core cam locks. They are sold in pairs to accommodate the exterior and the interior door prep.Ī-1 Bullseye Cabinet Lock Installation Jig #BUL-1 is designed for installing cabinet locks using 3/4”, 7/8”, 1-1/8” and 1-1/4” diameter cross bores. The hard anodized side plates are manufactured of aircraft alloy.Ī-1 offers 12 make and model-specific side plates for the Mortise Lock & Crosshole Jig. In addition to cutting the mortise pocket, the Mortise Lock & Crosshole Jig operates with optional A-1 side plates, which are templates providing drilling and routing locations for the crossbore holes and openings for the mortise lock trim. The jig is designed for cutting up to an eight-inch tall opening for the mortise pocket. Rotating the handle raises or lowers the cutter assembly. The cutter guide is attached to a threaded rod. It can accommodate three different backsets: 2-3/8”, 2-1/2” and 2-3/4”. This mortiser is self-centering, designed so the cutter automatically finds the centerline of a 1-3/8” to 2-1/2” thick door. The M-100 jig comes with a 1” diameter cutter for mortising the pocket and a 1-1/4” diameter cutter for mortising the faceplate opening. You can better control the positioning of the mortise pocket and the cutting tool can remove the excess wood from within the pocket easily and rapidly.Ī-1 Mortise Lock & Crosshole Jig #M-100 is designed to cut out the mortise pocket, to mortise the faceplate opening and drill the crossbore holes for the handle, levers or knobs, thumbturn, and mortise cylinder. Let me tell you a mortising jig is much easier and much faster. I have installed a number of mortise locks by hand and also using a mortising jig. This means that the holes must be drilled straight and slow enough to ensure the bit does not change direction and emerge into the light of day.Ĭutting out a mortise pocket in a door using a drill motor and an auger bit is difficult and time consuming. All of this drilling must be accomplished in a door that can be as thin as 1-3/8” thick. Once the holes have been drilled into the centerline of the door edge, A chisel is used to remove the web (the material left over between the holes). Fewer holes are required for smaller mortise lock cases. To create a mortise lock pocket by hand, drill the door edge several times using up to a 1-inch diameter auger drill bit (preferred tool) to a depth of about four to five inches. Over time, these savings will more than offset the price of the installation tool.įor this article, I will discuss three installation tools available from A-1 Security Manufacturing Corporation: Mortise Lock & Crosshole Jig #M-100, Cabinet Lock Installation Jig #BUL-1 and Bulls Eye Installation Tool for Cylindrical Locksets #BUL-2.
