CHOOSING THE RIGHT DRAWER SLIDE
Understand your drawer slide options
Side-mount: Sold in pairs or sets, with a slide attaching to each side of the drawer. Require clearance – usually 1/2" – between the drawer slides and the sides of the cabinet opening.
Center-mount: Sold as single slides that mount under the center of the drawer.
Under-mount: Sold in pairs, they mount to the sides of the cabinet and connect to locking devices attached to the underside of the drawer. They're not visible when the drawer is open, making them a good choice if you want to highlight your cabinetry. Drawer sides typically can be no more than 5/8" thick, and space from underside of drawer bottom to bottom of drawer sides must be 1/2".
Slides most commonly come in sizes ranging from 10" to 28". For side-mount and center-mount slides, typically measure the distance from the front edge of the cabinet to the inside face of the cabinet back and then subtract 1". For under-mount slides, measure the drawer length.
3/4 extension: Part of the drawer remains in the cabinet.
Full extension: Allows drawer to open the full length of the slide.
Over travel: Allows drawer to open beyond full extension, providing complete access – even underneath countertops.
Slides typically are rated for 75, 100 or 150 pounds, though some are rated for less and some specialty slides can handle as much as 275 pounds.
Most slides have a zinc finish. Some also are available in black (great for entertainment centers), and some are available in white or brown.
"Wow factor" features
Push to open: Slides open with a nudge to the drawer front, eliminating the need for handles or pulls. An especially good option for modern kitchens, where hardware might not be desired.
Self close: Slides return the drawer all the way into the cabinet when drawer is pushed in that direction.
Soft close: Slides return the drawer into the cabinet softly, without slamming.
