Master Lock Co 2848DAT Receiver Coupler Lock Set

Product Description

The MASTER LOCK CO 2848DAT is a bent pin receiver and coupler lock set designed to secure trailer hitches and tow couplers in a single keyed package. The set fits a 0.625 inch receiver hole and includes an adjustable coupler latch lock. Both locks are keyed alike, meaning one key operates the receiver lock and the coupler lock. This simplifies key management for truck and trailer operators. Licensed trade professionals and fleet service technicians working in towing applications will find the unified key system reduces the number of keys required on the job.

This lock set is suited for use on standard trailer hitch receivers and adjustable ball mount couplers commonly found on light-duty trucks, utility trailers, and towing rigs. The 2848DAT is packaged as a set and pairs with the 2847 coupler latch lock design. The bent pin receiver lock fits a 0.625 inch receiver hole, making it compatible with widely used receiver sizes in residential and commercial towing setups. Install technicians and fleet maintenance crews are the primary users for this type of hardware.

Installation Notes

Installation does not require special tools — insert the bent pin through the receiver hole and engage the locking mechanism by hand.
