MILBOPAX Trailer Puck Locks — Black 2-Pack, Enclosed Shackle, Push-to-Lock with 6 Keys

MILBOPAX Trailer Door Lock puck locks are compact, enclosed shackle locks designed to protect trailer, van, and shed doors with a push-to-lock, keyed-alike system.

These two black puck locks combine a fully enclosed round-body design with aerospace-grade materials and a spring-loaded core so you can secure doors quickly and resist common tampering methods. Built for outdoor use, the anodized 6061 aluminum body and hidden shackle make them resistant to cutting, prying, and corrosion while the included six keys (three per lock) and keyed-alike option simplify access for teams or multiple vehicles.

How do these puck locks stop thieves from breaking into a trailer?

Unlike open-shackle padlocks, the enclosed puck body hides the locking mechanism and presents no exposed shackle to attack. The rounded, smooth surface reduces points for bolt cutters, pry bars, or crowbars to grip, increasing time and effort required for forced entry.

• Fully enclosed round-body hides the shackle and locking core.
• Hard-anodized 6061 aluminum resists corrosion and cutting attempts.
• Minimal protrusion prevents leverage with crowbars or cutters.

What makes the locking and keying convenient for frequent use?

The locks use a spring-loaded push-to-lock core so you can secure a door with one hand—no key required to lock. Each pack comes with three keys per lock and both locks are keyed alike, allowing a single key to open both units for fleet or multi-door convenience.

• Press-to-lock operation for fast, no-key locking.
• Three physical keys per lock included for backups or multiple users.
• Keyed-alike configuration means one key opens both locks.

Are these puck locks durable in outdoor conditions and heavy use?

MILBOPAX builds these puck locks from aerospace-grade 6061 aluminum with an anodized finish to stand up to rain, sun, and dust. The materials and machining reduce the chance of jamming while maintaining a lightweight profile suitable for regular commercial or recreational use.

• 6061 aluminum is stronger than common lock metals and resists warping.
• Anodized surface provides extra corrosion resistance in wet or salty environments.
• Precision core and finish minimize binding and ensure consistent operation.

How can I install and use these locks on my trailer or shed?

Installation typically requires a compatible latch plate or hasp designed for puck-style locks; the round body slides over the latch and the internal spring core secures it with a push. For vehicles with existing puck-compatible hardware, the process is quick—otherwise, a simple hasp upgrade provides a more secure mounting point.

• Slide the puck over the latch plate and press until it locks.
• Use the included keys to unlock from the outside when needed.
• Compatible with standard puck hasps or custom fabricated latch plates.

Who is this for: These MILBOPAX puck locks suit owners of enclosed trailers, cargo vans, utility vehicles, storage sheds, and fleet managers who want a compact, tamper-resistant locking solution. They are ideal for people who need quick one-handed locking, keyed-alike convenience across multiple locks, and a durable, weather-resistant option for year-round outdoor protection.
