Locking Full-Extension Drawer Slides, 40 in, 500 lb Pair

Heavy duty locking drawer slides keep large drawers stable and secure with a double-lock design that helps prevent roll-out during transport. Built from thick high-hardness steel with a galvanized finish, these full extension ball bearing slides are designed for smooth, controlled movement and reliable holding power in workshops, trucks, RV builds, cabinets, and industrial storage. The 3-fold telescoping action lets you access the full drawer depth while maintaining consistent alignment.

• Delivers up to 500 lb load capacity for tool drawers, equipment trays, and heavy storage builds


• Locks with a dual side press to help secure drawers against shifting on bumpy roads


• Glides smoothly via double-row ball bearings with nylon cushioning to reduce noise and bounce


• Extends fully with a 3-fold telescoping design to reach the entire drawer contents


• Fits side-mount installations; measure drawer depth (excluding face frame) before selecting length

When a standard slide flexes, sticks, or won’t stay closed in transit, upgrading to a full extension locking rail can protect your gear and save time on daily use. This pair is built for demanding applications like service trucks, RV drawers, shop cabinets, vending equipment, and industrial shelving where stability matters. Choose the correct slide length for your drawer depth and allow clearance for side mounting to ensure smooth travel and proper locking. Grab yours today and build a drawer that opens easily, holds steady, and stays put when you need it to.
