12 Inch Soft-Close Ball Bearing Slide For Compact Cabinet Drawers

This is a 12 inch full-extension side-mount ball bearing drawer slide from Knape and Vogt's 8450 series, rated 100 lb per pair and finished in zinc, with an integrated Force Management damper that settles the drawer closed quietly every time.

Key Features

• Force Management soft-close damping catches the drawer near the end of travel and guides it to a controlled, silent close — not a self-close spring, a true damped mechanism.
• Full extension brings the entire drawer out to the cabinet face, so nothing at the back is out of reach.
• 100 lb load rating per pair handles a fully loaded small-cabinet or bath vanity drawer without strain.
• Non-handed design means both slides in the pair are identical — no sorting left from right on the bench.
• Zinc finish provides standard indoor corrosion protection on a functional side-mount slide that sits alongside the drawer box.
• Poly-Pack packaging delivers one complete pair per bag with mounting hardware included, sized for the single-drawer job or the small run.

Where the 12 Inch Length Earns Its Place

A 12 inch slide is the right call for shallow-depth applications: bathroom vanity drawers, nightstand drawers, desk pencil drawers, and upper spice or utility pulls where the cabinet interior is 12 to 13 inches deep. At full extension, the entire drawer clears the opening so the back of a short box is as reachable as the front. The soft-close damper makes that closing motion quiet and controlled — a welcome upgrade over a standard-motion slide in a bedroom or bathroom setting where slam noise matters. Pair one 12 inch slide per cabinet side per drawer; the poly-pack includes both.

Steel, Zinc, and the FM Damper Module

The slide members are cold-formed steel with a zinc electroplate finish. Zinc is the workhorse finish for side-mount ball bearing slides — it protects against indoor corrosion and holds up through years of daily cycling. The Force Management damper module is integrated into the slide body; it is not a separate add-on that can shift or fall out of alignment. Knape and Vogt tests the 8450 FM series beyond 50,000 cycles including the soft-close mechanism, meeting KCMA, BHMA, and BIFMA performance standards. The 1/2 inch side clearance requirement is the same as a standard KV 8400-series slide, so the 8450 drops into the same drawer box without a different box width.

The Right Buyer for This Slide

Cabinet shops building vanity or bedroom cases with shallow drawer runs will find this slide handles the short-depth work that a longer soft-close slide would overhang. Contractors retrofitting soft-close into existing bath vanities — where the interior depth limits the slide to 12 inches — get a damped, full-extension upgrade without cutting a new drawer box. Homeowners replacing a single sticky drawer in a nightstand or small desk can order one poly-pack and be done. The non-handed design and lever disconnect keep the install straightforward regardless of the crew size.

Quiet, Damped Closing in a 12 Inch Package

For shallow-depth drawers where soft-close matters — vanities, nightstands, and compact desk drawers — the KV 8450 FM series delivers full extension and genuine damped closing in a 12 inch format that fits where longer slides simply cannot go.
