Locking Drawer Slides, 44 In, 500 Lb Full Extension, 1 Pair

500 lb locking drawer slides deliver secure, full-extension access for heavy drawers in workshops, trucks, RV builds, cabinets, and industrial storage. The dual side-lock design helps keep drawers closed during vibration and movement, while double-row ball bearings support smooth travel. Built from thick, high-hardness steel with a galvanized finish for corrosion and wear resistance, these side-mount slide rails are designed for demanding, high-load applications.

• Delivers up to 500 lb load capacity for heavy-duty drawers, equipment trays, and storage pull-outs


• Locks securely with a press-to-lock dual mechanism to help prevent slide-out during bumps and transit


• Extends fully with a 3-fold design so you can reach the entire drawer depth without digging


• Glides smoothly using double-row ball bearings plus nylon cushioning to reduce noise and rebound


• Fits side-mount installations; measure drawer depth before ordering to select the correct length

Upgrade a drawer that binds, rattles, or creeps open under load. These heavy-duty, full extension locking rails are built for stable performance in mobile and stationary setups—tool drawers, under-bed RV storage, truck drawer systems, shelving, and vending equipment. For best fit, measure your drawer and cabinet depth (excluding face frames) and choose a slide length that matches the depth of the drawer.
