I’m planning to build a shop cabinet with a bunch of drawers, each approximately 18” wide, 22” deep(front to back), and 3” to 12” high.The drawers will be used to store typical shop stuff: tools, boxes of nails and screws, cans of finishes, paint, etc.

I’m considering using 3/4-extension slides rated for 75 lbs. Will those be sturdy enough?

Are 3/4-extension slides adequate, or will I regret not using full-extension slides (despite the extra cost)?

As far as weight goes;
Get a bathroom scale and fill a comparably sized drawer and see what it weighs in at!

Personally, I would go with full extension, but that IS just an opinion!!!

I think you will regret not going with full extension slides.

Full extension is almost always the way to go.

I would use full extension slides. They will typically be rated for 100# for that size.

If it is a cabinet screwed to the wall – go full extension.

If you will fill the drawers with tools and screws – and think you may be “testing” the 75 pound limitof a cabinet on casters like Pinto – go 3/4 or your cart will tip when you pull out the drawer.

DrDirt, good point about cabinet type.

If it’s non-mobile, I agree with the full extension slides that others are recommending..

Full extension. You can buy them in bulk from Woodworkers Supply. It is their house brand, but they work pretty well. Or you could get spendy and buy the Accuride full extension Plus 1” so the entire drawer contents are accessible.

Whew, eighteen full-extension slides is no small investment. Thanks for the information, but I may need to rethink this…

Fancy drawer slides are expensive overkill

For my shop storage I put together a 2×4 frame with 2×2 drawer guide rails mounted inside.

The 22w x 24d drawers ride in the rails, which also keep them from tipping.

Clint, do the drawers slide freely, despite the slides being wood-on-wood?

How much dust do you deal with in your shop? I would normally suggest full extension slides also, but I’ve used 3 different type slides in the different cabinets I’ve used in my shop over the years, 3/4 epoxy coated slides(very inexpensive), Full extension side mount (100lb. rated) and the Blum undermount full extension. (very expensive for shop use).

All have pros & cons, but the biggest problem I had using the side mount full extension slides was the dust and dirt getting into the ball bearings and working very rough over a period of time. If your shop is pretty much dust free, then you shouldn’t have that problem.

3/4 slides will bug you at times when you’re trying to find things that got pushed to the back of the drawers.
I would think the slides would handle the weight in most cases unless you just load the devil out of them. I’ve never had a problem with weight in any of those drawers, just the inconvenience of dealing with the drawer only coming out 3/4.

The Blums have worked flawlessly even with all the dust in my shop, but again ridiculously expensive for shop use. The only reason I used them, they where some left over slides from a huge kitchen job I did.

Actually I’ve used wood on wood drawers in one of my work benches and they worked OK, but the drawers where fairly small and about the only thing they were used for was sandpaper, so I have no experience using them for larger items and weight.

22” for $5.91 a pair. 100 lbs, full extension.

Now, these are not accurides, but they are pretty decent slides at an excellent price

I use wood drawer guides and cover the wood with this low friction tape. Works fantastic…!

It’s good to be able to pull the whole drawer out and throw it on the bench for when you need to go rummaging for something. You can do that easily with wooden runners or piston fit drawers.
