500 lb Heavy-Duty Full Extension Locking Drawer Slides (1 Pair, 18")
Upgrade your storage game with these industrial-grade, full extension ball bearing drawer slides. Engineered for demanding applications — RVs, trucks, SUVs, workshop cabinets, shelving units, and vending machines — this pair delivers a rock-solid 500 lb load capacity with smooth, quiet operation every time.
Key Features
- 500 lb / 226.8 kg Load Capacity: Built from 0.77 in (19.5 mm) thick, high-hardness steel, these slides handle serious weight whether fully extended or closed. The galvanized finish provides long-lasting rust and wear resistance.
- Dual-Lock Design: A double-lock mechanism secures the drawer in place with a simple press — keeping contents firmly in position even on rough terrain. Far more secure than single-lock or no-lock alternatives.
- Smooth & Quiet Operation: Double-row ball bearings ensure effortless opening and closing. Nylon cushioning on the center slide minimizes noise and eliminates unwanted bounce.
- 3-Fold Full Extension: The 3-section telescoping design allows complete access to the full depth of your drawer — no more reaching into dark corners.
- Side Mount Rail: Easy side-mount installation compatible with most standard drawers and cabinets. Suitable drawer length: 18.5 in / 470 mm.
- CE Certified: Meets CE safety and quality standards for added confidence.
