While I was building the pull out trays for my latest project, I found it useful to improvise a right angle jig to hold the side pieces square while assembling the tray.
I first used the fence from my drill press table and the extension fence from my miter saw bench.
This worked, but was fussy to set up for each drawer. Also easy knock out of square.
I decided to try and make a couple of fences that used the dog holes to speed up the process.
Originally planned to make them out of wood. But then I found the red fences that I think will work better.
I bought a couple of 8” (the 14” were sold out) extruded aluminum fences the were being cleared out for $8 apiece.
Unfortunately when I built my bench 20 years ago I had no idea what distance to space my dog holes. Hindsight, I wish I had made the holes 6” apart instead of 8”.
Over the years I’ve added more holes as needed.
Yesterday I started to add a series of holes between the existing 8” spacing.

I made a spacer jig to reference off the existing holes and locate two of the new holes at a time
So far this is working well. 109 yesterday afternoon when I bailed on the project for the day.
