PACLOCK's 81-Series Patented Trailer Door Lock, High Security Rotating Disc, Manufacturer-Controlled Key Assigning, Exclusive Key Number, U-Pick! Keyed Alike w/ 1 Key, Black

PACLOCK's RD-81A Patented Trailer Lock is engineered specifically for swing door trailers, toy haulers, and trailer doors with flat bar handles. Its hidden-shackle design eliminates bolt cutter attacks, while the aluminum body resists angle grinders by melting and galling up the blade. Unlike traditional hockey-puck locks that fit inconsistently, the RD-81A is designed to fit >98% of trailer applications. Combined with PACLOCK’s RD cylinder technology, the RD-81A is ideal for trailer owners who require the highest level of security.Its advanced rotating disc cylinder delivers over two billion possible key combinations, guaranteeing no two customers will ever share the same key number. The RD-Series cylinder is impossible to bump and highly pick-resistant due to the anti-drill spin plate. PACLOCK’s RD-Series prevents unauthorized duplication by requiring a designated System Code to reorder additional keys or padlocks keyed alike. Without this code, orders will not be processed. New System orders will include a System Card containing a unique code required for reordering padlocks and keys. Existing customers who wish to add new key numbers to their system can do so under “Customize Now.” Each RD-Series cylinder is 100% made in the USA, with the entire padlock made in the USA with global components by a veteran-led, woman-owned manufacturer employing veterans and people with disabilities. The RD cylinder technology is used in the U.S. military’s General Field Service Padlocks and is formally approved under the Department of War’s Lock Program, meeting Federal Specification FF-P-2827A. PACLOCK is one of only two manufacturers worldwide to meet these rigorous standards. PACLOCK brings true high-security rotating disc technology to a wide variety of padlock styles, allowing a single high-security key system to protect trailer doors, containers, jobsite boxes, and receiver locks. Our product line continues to grow–if you don’t see your lock, call us.
