The Complete Trailer Lock Comparison

Off-the-shelf trailer locks may look convenient, but they leave money on the table for locksmiths – and serious gaps in security for customers. Introducing “LOCK TALK,” a new mini-series within our Locksmith Series videos. In this episode, BWAUGH breaks down the padlocks you should be offering customers with a Delta® 300 Series cargo trailer – highlighting where common locks fall short and how PACLOCK systems create better control, stronger margins, and repeat business. Why it matters for locksmiths: PACLOCK isn’t a one-time padlock sale. It’s a scalable, keyed-alike system that keeps customers coming back. From couplers and hitches to doors and chains, PACLOCK lets you secure the entire trailer under ONE KEY using serviceable, rekeyable hardware engineered for the job. PACLOCKs for Trailers: • “77-Series” Trailer Coupler Lock: Common coupler locks used in storage often fail under basic attacks. PACLOCK’s patented & patent-pending two-piece design and 304 stainless cone puck address those weaknesses.

The “79-Series” provides consistent latch security across unique coupler designs, including the Bulldog® bumper pull coupler on this Delta® trailer.

PACLOCK’s interchangeable “80-Series” pins support more receiver sizes and use cases with a single padlock body.

The patented 81-Series is purpose-built for swing-door trailers, with a hidden-shackle design that seats correctly every time.

PACLOCK’s block-lock and square-link chain removes exposed attack points while tying into the same key system as the rest of the trailer.
