20 in Soft Close Drawer Slides 6 Pairs - 100 LB Capacity Smooth Action

In this review of the 20 in soft close drawer slides, the bottom line is simple: these slides suit DIYers and homeowners who need heavy duty, smooth drawer action at a budget-friendly price. The reviewer found the hydraulic damper reliably delivers a quiet soft close and the solid ball bearings make openings feel smooth and consistent. While installation can be fiddly for some, the overall build quality from cold-rolled steel and zinc plating gives a sense of durability that makes these slides worth considering for kitchen, workshop, or office drawers.

Key Features

• Soft close mechanism: The hydraulic damper provides a controlled, quiet close that reduces slamming and protects drawer contents.
• Heavy duty construction: Made from high grade cold-rolled steel with a zinc plated finish for corrosion resistance and long service life.
• Ball bearing action: Solid ball bearings create smooth opening and closing motion that feels consistent across repeated use.
• 3-fold full extension: The three-stage rail allows the drawer to reach a full open position for better access to the drawer interior.
• Detachable section: A plastic release buckle on the rail makes it easy to separate the narrowest section for drawer removal during installation or maintenance.
• High load capacity: Rated to support up to 100 LB, suitable for heavy kitchen or tool drawers where weight is a concern.

Who It's For

These slides are aimed at homeowners, cabinet makers, and hobbyist woodworkers who need a robust side mount slide that offers soft close and full extension for drawers up to 20 in deep. They are a practical choice when replacing worn hardware in kitchens, bathrooms, offices, or tool chests where durability and smoothness matter.

Those looking for ultra-easy, tool-free installation or a drawer slide with an integrated face-frame mounting system should look elsewhere, as these are side-mount slides and some installers report the rail removal and alignment can be fiddly on the first attempt.
