NAKANEKO Plastic Gladhand Lock 12-Pack — Keyed-Alike Trailer Emergency Coupling Security, Weather-Resistant

NAKANEKO Plastic Glad Hand Lock is a keyed-alike 12-pack designed to secure a trailer’s emergency gladhand and reduce unauthorized coupling.

Keep your semi trailer connections safe with a simple, weather-resistant plastic gladhand lock that comes as a matched set of 12 locks and 24 keys. Built for fleets, contractors, and owner-operators, these compact locks attach to the emergency side gladhand to deter theft, prevent accidental trailer movement, and improve worker safety during loading and parking.

How does this gladhand lock stop unwanted trailer coupling?

The lock slips over the emergency gladhand coupling and fastens with a keyed cylinder, blocking another tractor from connecting. Because the set is keyed alike, one key opens any lock in the pack, which speeds access for authorized personnel while keeping outsiders out.

• Blocks mechanical mating of gladhands to prevent towing
• Keyed-alike convenience: one key for all 12 locks
• Includes two keys per lock for backups or shared access

What are the materials, size, and weather resistance?

These gladhand locks are molded from durable plastic engineered for exterior use; they resist corrosion that affects metal alternatives. Each lock measures approximately 2.5 × 1.4 × 3.3 inches (L×W×H), a compact profile that fits most standard emergency gladhands.

• Durable plastic construction reduces rust and wear
• Compact dimensions for universal gladhand compatibility
• Lightweight design eases handling and storage on the vehicle

How easy is it to use and manage on a fleet?

Installation requires no tools: place the lock over the gladhand and secure it with the key to engage the cylinder. Because the pack is keyed alike, fleet managers can distribute one key per driver or depot, simplifying logistics and reducing the number of keys to track.

• Tool-free installation and removal with the included keys
• Keyed-alike system reduces key management complexity
• Two keys per lock provide immediate spares for fleet use

What practical safety and operational benefits can you expect?

Using a gladhand lock helps prevent unauthorized movement of trailers and protects loaded goods from opportunistic theft. The visible lock also communicates that a trailer is secured, which helps maintain safer working zones during loading and downtime.

• Deters opportunistic trailer theft and tampering
• Enhances on-site safety by preventing accidental coupling
• Ideal for parked trailers, overnight yards, and staging areas

Who is this for: The NAKANEKO Plastic Glad Hand Lock 12-pack is intended for fleet operators, owner-operators, logistics coordinators, and contractors who need a low-cost, easy-to-manage way to secure multiple trailers.
