I bought these slides:,43614,43616&ap=1

But I have no idea how wide I am to make the drawer relative to the drawer opening.. The instructions don’t say….

I always use KV slides (TT 100), very similar to what you have bought, mine are also ball bearing and I believe that with this type of glide and probably same with yours you would want to build the drawer 1” under sized to the drawer opening. So if you have 20” opening then build your drawer 19”. There should be a 1/16 +/- tolerance but the more accurate your dimensions the better and ensure your drawers are all square, you should have no problems. The glides can be ‘finicky’ if you are not used to using those but I love the ball bearing feel and how they work.

Jerry is right, but I might check with Lee Valley for sure. All the slides I have seen of this type require 1/2” clearance per side. It’s been my experience, that going a little more than the 1” under for the drawer size is better. Not much though. If the drawer is a little loose, you can shim the guide. If it’s too tight, you must sand the side of the drawer, and that is a real pain.

I’d guarantee they are 1/2” thick each. Therefore the 1” less dim. would be correct.

If you’ll notice the glides have mounting locations that are essentially tabs. If you mount to the farthest point out on the tab it will give when an undersized draw is installed. So, building the drawer just a touch light makes them fit right every time.

All slides I’ve used are typically 1/2”- no matter what brand- so the drawere should be 1” smaller. I usually shoot for 1 1/32” smaller. I can always add on to fit the drawer but removing material is a bit harder . I have always come out okay using that premise.

DITTO to eveything stated above. I’m glad the ball-bearing slides were invented. I really hate them old cheap crappy thin white slides. I v’e had to use them when I ran out of b.b in a pinch. All my shop furniture has b.b slides. It’s the only way to go.

There’s a link to instructions for the 12” sides. 1/2” is correct.

Jerry – where do you get your KV TT100 slides?

Have your say...
