These slides gradually slow the drawer's motion to prevent it from slamming open. When you don't have enough clearance for side-mount or under-the-counter slides, mount these to the base of your drawers. The slides only extend _3/4 of the closed length to reduce the chance that a heavy load will tip your cabinet. They also have a pull-out release, so a brake will stop the slide components from coming apart when the drawer is extended. If you need to remove the drawer, pull forcefully to separate the slide parts. All have ball bearing rollers for smooth, quiet operation. Made of stainless steel, they resist corrosion and are commonly used in environments that may get wet or require regular cleaning.
