These full-extension undermount drawer slides feature an integrated hydraulic soft-close system, 3D adjustable locking devices, and durable galvanized steel construction. With a load capacity of up to 100 lbs, they are designed for compatible face frame cabinet applications where a clean, concealed drawer-slide installation is preferred.

Key Features

Concealed Undermount Design

Unlike side-mount drawer slides, undermount slides are installed beneath the drawer and remain hidden when the drawer is opened.

The concealed design creates a clean, streamlined appearance while helping maintain a neat look inside cabinets and furniture.

Full Extension for Complete Drawer Access

The full-extension rail system allows the drawer to open fully, making it easier to see and reach items stored at the back.

This is especially useful for kitchen cabinets, storage drawers, bathroom vanities, and other applications where full access is important.

Soft Close for Smooth, Quiet Closing

The integrated hydraulic soft-close damper controls the drawer during the final stage of closing.

Instead of slamming shut, the drawer slows down and closes smoothly and quietly, helping reduce impact and everyday noise.

3D Adjustable Locking Devices

The included 3D adjustable locking devices provide multiple adjustment directions to help achieve accurate drawer alignment.

The adjustment system can help fine-tune drawer positioning after installation for a more precise fit and consistent appearance.

Heavy-Duty 100 lb Capacity

Made from durable galvanized steel, these undermount drawer slides are designed to support up to 100 lbs when properly installed and used under suitable conditions.

The reinforced construction provides stable support for compatible drawers and everyday cabinet storage.

Adjustable Installation Design

Elongated and bottom-mount installation holes provide additional adjustment flexibility during installation.

Rear mounting brackets help secure the rear of the slide and provide stable support inside the cabinet.
