Short Answer
Do locking drawer slides lock open and closed?
Many heavy-duty locking drawer slides are designed to lock closed and lock fully open, but the exact behavior depends on the slide. Confirm whether the slide has lock-in, lock-out, both end positions, and whether it locks only at the ends or at intermediate points.
Direct answer
Lock-in means the slide holds the drawer closed. Lock-out means the slide holds the drawer fully extended. These are useful for truck drawers, RV trays, camper pull-outs, generator trays, and mobile work surfaces where movement control matters.
What to confirm before buying
When locking slides are worth using
Locking slides are worth using when the drawer could move on its own or when the open drawer needs to stay stable. Truck bed drawers, RV fridge trays, trailer storage, overland cargo systems, and mobile work trays are common examples.

Do locking slides lock halfway?
Most locking drawer slides lock only closed and fully extended. If halfway locking is required, confirm that feature before ordering.
Do truck drawers need locking slides?
Locking slides are strongly useful for truck drawers because they help prevent unwanted movement while driving and while the drawer is open on uneven ground.
What is the difference between lock-in and lock-out?
Lock-in holds the drawer closed. Lock-out holds the drawer fully extended until the release is operated.
