Drawer Slides with Lock, 20 in, 500 lb, Full Extension

Heavy duty locking drawer slides keep large drawers stable with lock-in/lock-out control, so heavy loads stay secure at full extension. This 1-pair side-mount set uses a 3-fold full-extension design to reach deep storage without struggling. Built from cold rolled steel with a zinc-plated finish, it’s designed for industrial drawers, cabinets, shelves, RV and truck builds, and equipment bays where smooth travel and reliable holding power matter.

• Delivers 3-fold full extension for easier access to the back of deep drawers and cabinets


• Locks in and locks out to hold the drawer closed or fully open for safer loading and servicing


• Supports up to 500 lb / 227 kg capacity with thick cold rolled steel construction


• Slides smoothly with double-row ball bearings plus nylon buffer for quieter, low-bounce travel


• Includes mounting hardware for quick side-mount installation on cabinets, machines, and vehicle builds

When you’re upgrading a shop drawer, building a pull-out shelf, or fitting heavy storage into an RV, truck, or commercial cabinet, slide choice determines safety and usability. These full extension, ball bearing slides are made for demanding installs where standard cabinet hardware won’t hold. Measure drawer depth and cabinet length before ordering (slide length should be less than drawer depth). Grab yours today and finish your build with a secure, lockable glide.
