3d Printed Jig Guide - for  Briton 5400 Series 5420 5430 Std/Radius

This jig is designed to be used with the following Briton models:
  • 5420.60.S Sashlock - 89mm case (60mm backset)
  • 5420.60.R Radius Sashlock - 89mm case (60mm backset)
  • 5430.60.S Bathroom - 89mm case (60mm backset)
  • 5430.60.R Radius Bathroom - 89mm case (60mm backset)
Although the main jig can be used with the 5410, 5440 and 5470 variants, the keeper is different. We have not yet developed a jig for these strike / keepers. Please get in ouch if you require a jig for one of these models.

We also offer the RADIUS version these latches - simply select 'RADIUS' in the shape option above.

These latches have a 235x20mm face plate, 185x25mm keeper. The latch is not included. Can be used on all doors between 35mm and 54mm due to adjustable fences. The fence that comes with the jig had the pilot holes for both the 55mm and 60mm backset variants of these locks.

This listing is for a kit that contains both the jig for the main face plate, as well as the jig for the strike plate / keeper.

The main jig is designed to be clamped to a door and results in a perfect latch recess. The slim jig (more details below) is designed to be screwed to the door frame.

The main jig allows for the latch faceplate recess to be cut, as well as pilot holes for:
  • Faceplate mounting screws
  • Door handle centre (and bolt-through door handle holes)
  • Door keyway centre
Pilot holes are 3mm and can be drilled or marked with a Pica pencil.

The 'flap' also allows for initial routing / cutting of the recess for the lock main body. 

These jigs come as a kit which includes the standard latch jig along with a 'slimline' strike plate / keeper jig. The slim jig is designed to be used on door linings/frames when the door stop and architrave are in place (although it can obviously be used on frames where the door stop and architrave are not in place). This jig features a short fence and smaller deck (with a removable extension) so as to not interfere with the door stop. The deck thickness is 15mm. When used with door stop thicker than this, the jig will need some shims or the door stop will need to be removed. The fence on this jig is adjustable to allow for correct positioning of the keeper. The 'flap' on the keeper allows for the tidy box recess to be cut as well as the pilot holes for the keeper mounting screws.

Lightweight and easy to use. Printed in durable PETG. All hardware included is A2 stainless steel.

Designed to be used with a 12-13mm template router cutter (such as the Trend 1/4" Template Profile Router Cutter 12.7 x 9.5mm shown in the photos). The cutter is not supplied with the template.

These jigs use a very similar process to our tubular latch jigs. Please see that listing for a video on how to use the jigs.

Process
  1. Install your cutter in your router and set the depth to match the thickness of your latch faceplate
  2. Adjust the fence so that the jig is central on the door edge (use the marks to line up the jig with the door edge centre line)
  3. Position the jig at the required height and clamp the jig in place
  4. Router the faceplate recess and use a chisel to finish the corners
  5. Before unclamping the jig, swing the flap across the face and pilot drill (use a 3mm drill or Pica pencil) the holes in the face
  6. Router the slot for the main lock body (to a reasonable depth)
  7. Pilot drill the door handle centre hole and lock centre hole (carefully choose the correct backset hole)
General Notes

The colour of the template may vary based on materials in stock when your order is placed.

As with any template, we strongly recommend you try the template on a spare piece of wood first to ensure it's compatible with your latch and cutter. If the latch face plate is a little tight, use a file or some sandpaper to gently remove some material from the inner faces of the jig.

Always secure the jig, then position the router carefully within the jig before switching it on. Equally, ensure the router has fully stopped before removing it from the jig. This will prevent damage to the jig.
