500lbs Heavy-Duty: Made of 0.77 in/19.5 mm thick high hardness steel, the heavy duty drawer slides have a weight capacity of up to 500 lbs. The galvanized finish makes the telescoping drawer slides rust and wear-resistant for long-time use. It can be used in shelving, cabinets, industrial drawers, RVs, trucks, vending machines and more.

Double Lock Design: The full extension dresser drawer slides are equipped with a dual locking design that locks the slides with a simple press, ensuring that your items are secure and won't slip off even in bumpy roads.

Gentle & Quiet Lock Slides: These slides feature a locking and latching design that is easy to control. Unlike slides with no lock or only one lock, our double-lock design provides greater security and stability. Double-row ball bearing provides smooth sliding when closing and opening drawers. Nylon cushioning on center slides is designed to produce less noise and won't bounce.
