We use steel ball-bearing 100Lb. rated slides.
x10 and x11 drawers all use 10" full-extension slides with 10.5" of travel. You can access all containers on the drawer.
x22 drawers use 22" full-extension slides with 22" of travel.
All drawers on slides are easily removed with a quick lever push on the slide. The slides then push back on and click into place to prevent pulling off.
