Square Cut Rebate

 

system-2

Square cut with rebate – 2 sizes of profile are required with the transom bar narrower than the mullion. Panels are assembled using continuous mullions which are drilled at the transom position(s). Joints are made using a pin through the mullion with mating connectors inside the transoms. The rebate in the edge of the wider mullion bar hides the cut edge of the transom. This type of panel can be produced almost as quickly as ordinary square cut & key panels and requires only a saw and drill with measuring jig. The resulting panel is very rigid and any colour can be produced without the need for special keys.

The process for a basic 6 pane georgian panel is as follows:

1. Cut mullion to length

2.Drill or notch mullion at transom positions

3. Insert pin through holes in mullion and fit sleeves to either side of each pin

4. Cut transom bars to length

5. Assemble transom bars to mullion

6. Fit edge keys to mullion and transoms
