wtnhighlander Posted February 22, 2019 Report Share Posted February 22, 2019 Those of you that have experience building kitchen cabinets: what is the longest, full-extension, undermount or centermount ball-bearing drawer slide I can use in a box that is 26" deep (24.5" inside)? From what I see on the supplier's web sites, it appears to be 21", but I'd like to hear you experience. Thanks. Quote Link to comment Share on other sites More sharing options...
..Kev Posted February 22, 2019 Report Share Posted February 22, 2019 I'm pretty sure I've bought 24" before but, don't recall the supplier. They may have been local, I just don't recall. Regardless, I know they're out there... Quote Link to comment Share on other sites More sharing options...
Larry Moore Posted February 22, 2019 Report Share Posted February 22, 2019 I'm sure Blum has 24" but it depends on how you mount them as to size you can use. Mounted directly to the side you can use a longer slide than ones using that bracket in the back. 1 Quote Link to comment Share on other sites More sharing options...
Chestnut Posted February 22, 2019 Report Share Posted February 22, 2019 Just because you use a 21" slide doesn't mean the drawer can only be 21" you can put a shorter slide on a longer drawer. I usually get 22" but that is because i make my cabinets to 24" outside and want to leave a bit of space inside. For you a 24" slide should be possible with 1/2" of fluff space. 1 Quote Link to comment Share on other sites More sharing options...

mat60 Posted February 22, 2019 Report Share Posted February 22, 2019 I haven't used under mount. When Im building 24 inch base cabinets I use KV 22 inch side mount and my drawers are 22 inch deep. 1 Quote Link to comment Share on other sites More sharing options...

But that wouldn't allow full extension of the drawer, correct? Quote Link to comment Share on other sites More sharing options...
wtnhighlander Posted February 23, 2019 Author Report Share Posted February 23, 2019 Anyone recommending a particular model - my client wishes to avoid self/soft closing units. Basic ball bearings only. Quote Link to comment Share on other sites More sharing options...
wdwerker Posted February 23, 2019 Report Share Posted February 23, 2019 Most undermount slides ,even the ones without soft close have a self close, that's what holds the drawer shut. Usually undermount slides have a pin or hook that goes into the back of the drawer. This means that the drawer length is fixed by the slide you choose. I've gotten 26" Blum concealed slides. There are also heavy duty versions for big drawers. Some ball bearing side mount slides can also be used as undermount. 100 lb rating side mount is maybe 40 lb or less when undermount did. 2 Quote Link to comment Share on other sites More sharing options...
DerekMPBS Posted February 26, 2019 Report Share Posted February 26, 2019 I ordered Promark slides from Amazon, which are available in 2" increments from 10" up to 28". The are full extension, ball bearing slides. Currently, a 10 pack of 24" slides is going for $66. 1 Quote Link to comment Share on other sites More sharing options...
wtnhighlander Posted February 26, 2019 Author Report Share Posted February 26, 2019 Those Promarks look pretty nice, especially for the price. But all I see are side mounts. Quote Link to comment Share on other sites More sharing options...
