20 in 3-Section Full Extension Ball Bearing Drawer Slides - 6 Pairs

In this review of the 6 pairs of 20 in 3-section full extension ball bearing side mount drawer slides, the bottom line is straightforward: these are heavy-duty, budget-friendly slides for anyone refurbishing cabinets or building drawers that need full extension and quiet operation. The review finds them best for DIYers, cabinet makers, and homeowners fitting kitchen base cabinets where smooth glide and durability matter. The single biggest reason to buy is the solid cold rolled steel construction with zinc plating that delivers robust, long-lasting performance for everyday drawers.

Key Features

• Six pairs per pack: Provides enough slides for multiple drawers or a full kitchen refresh without buying individual pairs.
• Full extension: The 3-section design lets drawers open fully so contents at the back are accessible without removing the drawer.
• Ball bearing side mount: Steel ball-bearing action creates a smooth, reliable glide and reduces sticking under load.
• Zinc plated steel: Cold rolled steel with zinc plating resists rust and stands up to heavy use in kitchens and workshops.
• Quiet closing: A black buckle on the third channel and nylon rubber components reduce noise during opening and closing.
• Mounting screws included: Basic screws come with the slides so installations can start right away, with extra screws available separately if needed.

Who It's For

These slides are ideal for homeowners doing a cabinet repair, carpenters building new drawers, and DIY renovators who need 20 in slides that support heavier loads. The 100 lb capacity and full extension make them a practical choice for kitchen base cabinets, tool chests, and storage drawers where durability and access are priorities.

They are less suitable for installations that require face frame brackets unless the installer purchases rear mounting brackets separately, and users who need predrilled specialty brackets or an integrated soft-close mechanism should look elsewhere.

Pros & Cons

Cons

• Screw quality is mixed according to some buyers, so many will replace screws for a more secure fit.

Frequently Asked Questions

How do I choose the correct length?
Measure the internal length of your drawer box without the face frame; choose a slide 1 in shorter if lengths are uneven and ensure the slide length does not exceed cabinet depth.

Do mounting brackets come with the slides?
No, rear mounting brackets for face frame cabinets are not included and must be purchased separately when required.

Are the included screws good enough?
The slides include mounting screws, but feedback is mixed and some installers prefer to use higher quality replacement screws for a more secure installation.
