20 inch Drawer Slides 4 Pairs Soft Close Full Extension - Smooth 100

In this review of the 20 inch Drawer Slides 4 Pairs set, the bottom line is simple: this kit is best for homeowners or hobbyists who need heavy-duty, side-mounted rails that deliver full access and a quiet close. The package includes four pairs (8pcs) of 20 in soft-close drawer slides with screws, and the most compelling reason to buy is the combination of 3-fold full extension and a reliable soft-close mechanism that lets you access the entire drawer while limiting slam and noise.

Key Features

• 4 pairs soft close drawer slides: The set includes four pairs (8pcs) of 20 in self-close slides and matching screws so multiple drawers can be upgraded at once.
• 3-fold full extension: The three-stage telescoping design allows the drawer to be pulled out completely for full access to contents.
• High-grade material: Made from cold rolled steel with electro zinc plating to resist rust over long-term use.
• 100 LB capacity: Steel ball-bearing action and continuous bearings provide smooth movement while supporting heavy drawer loads.
• Detachable third track: A plastic buckle on the back allows separation of the narrowest track for easier removal and cleaning.
• Side mount guidance: Designed for side installation with notes on face frame and faceless cabinets to help with correct fitment.

Who It's For

This product is aimed at DIYers, cabinet makers, and homeowners who want to retrofit or build dresser, kitchen, or workshop drawers that need full extension and a quieter close. The included screws and four-pair quantity suit small renovation projects where multiple drawers are being upgraded at once.

Those who should look elsewhere include buyers who need undermount or center-mount slides, very shallow cabinet depths where a 20 in slide exceeds case depth, or users who require a different soft-close feel; some customers noted mixed experiences with the force required to open or the perceived slide quality.

Pros & Cons

Cons

Will the slides rust over time?
The rails are made from cold rolled steel with electro zinc plating to resist rust, offering long-term corrosion protection.
