Master Lock 2848DAT Key-Alike Receiver & Coupler Lock Set – 2-Piece Security Bundle

Protect your trailer with a reliable two-piece lock set

The Master Lock 2848DAT key-alike set brings together two rugged components designed to deter tampering and provide straightforward access when you need it. The receiver lock features a chrome-plated shackle and sleeve, while the coupler lock offers an adjustable stainless steel shackle and case. Hardened receiver pins and precision locking mechanisms contribute to strong, dependable security without complicating daily use. These elements work together to help you secure unattended trailers, cargo haulers, or other 5/8 inch receiver applications on the road or at home.

What’s included and how it helps

• Receiver lock with bent pin for reliable alignment in 5/8 inch receiver tubes
• Coupler lock with adjustable stainless steel shackle for flexible sizing
• Four keys that fit both locks for easy access and minimal key juggling
• Protective case for organized storage and transport

Key benefits are designed to be practical and clear. The set is described as keyed alike, meaning a single key system can simplify access and reduce fumbling when you’re on the move. A quarter-turn action offers quick locking and unlocking, saving time at the campsite, loading dock, or highway rest stop. The materials chosen—chrome plating, stainless steel, and hardened pins—contribute to durability while maintaining a clean, professional appearance on your equipment.

Core features at a glance

• Two components keyed alike for convenient access
• Pick-resistant precision locking mechanisms to deter tampering
• Chrome-plated shackle on the receiver lock for corrosion resistance
• Adjustable, stainless steel shackle on the coupler lock for flexible setup
• Four keys included to cover both locks and spare access
• Easy installation and handling with straightforward setup

In everyday use, these locks offer flexibility and confidence. The 5/8 inch receiver compatibility helps keep alignment and security consistent across standard trailer hitch setups, while the adjustable coupler latch lock accommodates common variances in hitch assemblies. While no lock can guarantee absolute security, the combination of material quality, a keyed-alike system, and a simple, fast operation makes this Master Lock set a practical option for protecting trailers and related gear.

Real-world use cases

• Securing an unattended trailer at a campsite or job site
