Full Extension Drawer Slide FAQ

Full Extension Drawer Slide carries a drawer on ball bearings or rollers, giving smooth, load-rated extension and consistent alignment. It is specified by length, extension type, mounting type, and load capacity.

Side-mount slides fix to the drawer sides and need about 1/2" clearance per side; undermount slides hide beneath the drawer for a clean look and are common on premium cabinetry. Undermount requires more precise drawer sizing.

A full-extension slide lets the drawer pull out its entire depth so you can reach the back; over-travel extends slightly further. Partial (3/4) extension is cheaper but leaves the back of the drawer under the cabinet.

Ball-bearing slides run on steel bearings for smooth, quiet, load-rated motion and longer cycle life than roller slides. They are the standard for soft-close and heavy-duty drawers.

Choose the slide length for your cabinet depth, the mounting type (side, under, bottom, or center), the extension (full or partial), and the load rating for the drawer contents. Confirm the side clearance available in the opening.

Yes. Heavy-duty, full-extension, locking ball-bearing slides (rated well above the drawer load) are the right choice for tool cabinets, truck storage, and industrial drawers.

Choose a slide length 1–2 inches shorter than your cabinet interior depth. Common lengths run 12" to 24" in 2" steps, with heavy-duty options to 28". Measure the usable depth behind the face frame.

Standard side-mount slides need 12.7mm (1/2") of clearance on each side of the drawer, so the drawer box is 1" narrower than the opening. Always confirm against the specific slide.

Light-duty slides hold roughly 35–45 kg, standard slides 45 kg, and heavy-duty slides 70–135 kg per pair. Choose a rating above your loaded drawer weight.

Common materials include Stainless Steel, Carbon Steel, Zinc Alloy, Aluminum, Brass, Copper. The right material for full extension drawer slide depends on load, corrosion exposure, and target price.

Available finishes include Matte Black, Brushed Nickel, Satin Nickel, Polished Chrome, Satin Chrome, Antique Brass. Finish affects appearance, corrosion resistance, and cost.

Mount the cabinet member level and square, fix the drawer member to the drawer side at the matching height, engage the drawer, and test full travel and soft-close before locking the pattern.

Use a spacer jig or mounting line so both slides sit at the same height and parallel to the cabinet front. Mount the cabinet member first, then the drawer member, and test travel.

Usually the slides are not parallel, the drawer is racked, or there is debris in the bearings. Re-check that both members are level and at equal height, and that the drawer box is square.
