Heavy Duty Base- and Under-Mount Drawer Slides



Mounting to the tops and bottoms of drawers, these steel slides support drawers even if they’re tall and hold heavy equipment. They’re often used in kitchens and other washdown areas because they’re powder-coated to resist rusting and their ball bearings are encased to keep out liquid. The encased ball bearings also distribute weight more evenly than standard ball bearings, which means they’re quieter and support more weight. To keep the bearings from wobbling or falling off track due to heavy loads, these slides have rail guides. Slides maintain a constant amount of support as you fully extend them, so accessing deep inside drawers isn’t a problem. All are LGA tested according to DIN 4554 for safety, performance, and quality.
Add slow-closing attachments to keep drawers from slamming.

Soft-Closing Heavy Duty Base- and Under-Mount Drawer Slides


To prevent drawers from slamming shut and support them even if they’re tall and full of heavy equipment, these steel slides have soft-closing bumpers and mount to the top and bottom of drawers. They’re commonly used in washdown areas such as kitchens because they have a powder coating to prevent rust and their ball bearings are encased to keep liquid out. Since they’re encased, the ball bearings spread weight more evenly than standard ball bearings, which makes them quieter and support more weight. To make sure the bearings don’t wobble or fall off track because of heavy loads, these slides have rail guides. Slides maintain a consistent amount of support as you fully extend them, so reaching deep inside drawers isn’t an issue. All are LGA tested according to DIN 4554 for safety, performance, and quality.

Heavy Duty Sleeve Bearing Carriages for T-Slotted Framing
Threaded inserts secure the bearing to the carriage and prevent it from loosening due to frequent starts and stops. Carriages are suitable for washdown environments. Mate with a T-slotted rail to add linear motion to your assembly. Note: Carriages cannot be used upside down, vertically, or on their side.
T-slotted rails can be easily cut to length and drilled for mounting.
View additional T-slot hardware and accessories.
Hand brakes mount on the carriages to hold them in place on the rail. Drill a hole in the carriage to mount.
End caps mount on the rails to prevent overtravel.
T-slot fasteners (sold separately) let you mount components to the carriages.
