The fingers on the Lock Jig allow the jig to be lifted off the door edge by up to 6mm. This prevents the guide bush from catching the door.


Yes and no because although the mortise could be recessed the faceplate would require some work with a chisel to finish it off. Also special sizes of plate may be required.


No you can use the collar that comes included with the Lock Jig. This fits over the top of the GB160, which will then increase the diameter to 30mm.


No, not without re positioning.


If you fit a GB240 guide-bush, which has a 24mm diameter and longer spigor) and use a 20mm diameter cutter e.g. Ref: TR20DX1/4TC then it will work because the offset between the cutter and the guide-bush still remains 2mm each side.


Length min = 2 5/8" - max. 5" , Width min = 3/8" - max. 1 3/8"


A 30mm guide bush is required reference number GB/30/A.


The corners need to be squared with a chisel because the router cutter leaves a radius. We offer a corner chisel ref. C/CHISEL which has a High Speed Blade for this purpose. The chisel is placed in the recess and hit with a hammer, this creates a square corner.

No, due to safety reasons, 63mm cut depth and 115mm overall length is all that is available e.g. 3/75X1/2TC, TR37X1/2TC, C172X1/2TC.


Protection times are 10mm = 1/2 hour (30 mins), 15mm = 3/4 hour (45 mins), 20mm = 1 hour (60 mins).


You can cut out the remainder of the depth by using a auger bit.


To work from the face of the door use cutter 346X1/2TC, or if you want to work on the edge of the door use cutter 3/6X1/4TC.
