Yujanery Plastic Glad Hand Lock - 3-Pack Keyed-Alike, Corrosion-Resistant

The Yujanery Plastic Glad Hand Lock is a keyed-alike, three-pack locking device that secures your trailer’s emergency glad hand to deter theft and accidental movement.

Designed for fleets, owner-operators and equipment yards, this compact plastic lock slips over the emergency airline glad hand to prevent coupler movement and unauthorized towing. Lightweight and corrosion-resistant, the set arrives keyed alike so all three locks open with the same key—making inventory and daily access simpler for drivers and maintenance teams.

How does this glad hand lock protect my trailer when parked?

By physically blocking the emergency glad hand, the Yujanery lock prevents the air coupler from being engaged or moved, reducing the chance of an unauthorized hookup or accidental separation. It acts as a visible deterrent and a simple mechanical barrier that’s quick to install.

• Fits over standard emergency glad hands to stop coupling movement
• Visible bright color signals the trailer is secured
• Keyed-alike set simplifies unlocking across multiple trailers

Will a plastic lock hold up in outdoor and fleet environments?

Yujanery uses durable engineered plastic that resists rust and stands up to road grime and weather exposure better than untreated metal. While lightweight, the construction is designed for routine fleet use where corrosion resistance and ease of handling are priorities.

• Non-corrosive material for long outdoor life
• Lightweight for quick handling during inspections
• Bright finish remains visible after repeated use

What does 'keyed alike' mean and why is it useful?

Keyed alike means all three locks in the pack open with the same key included in the order, so you don’t need different keys for each lock. This decreases time spent searching for the correct key and reduces the number of spare keys you must manage.

• One key opens all three locks included in the set
• Less key inventory for drivers and yard staff to carry
• Easy rekey or replacement procedure if needed

How easy is it to use this lock during daily ops?

Installation is straightforward: place the lock over the emergency glad hand and snap or latch per the design to secure. Removal is just as quick with the matching key—ideal for pre-trip checks and loading operations where speed matters.

• Tool-free installation for fast application and removal
• Compact shape stores easily in glove compartments or toolboxes
• Three-lock quantity supports multiple trailers or spare units
