TowWorks Trailer Hitch Lock Set Keyed-Alike 5/8" Extra-Long 3-1/4" Span, 2-Pack - Tubular Keys & Cotter Backup

This two-pack of TowWorks locking hitch pins offers heavy-duty theft deterrence and user-friendly operation for trailers, tow vehicles, and cargo carriers that require a longer pin than standard models. Each unit features a push-and-turn tubular key mechanism, rubber O-rings to reduce rattle, and an included spring clip (cotter pin) for backup retention. The package comes keyed alike with four keys per lock, so both pins open with the same key and you have spares available.

Will this lock fit my hitch and receiver?

The TowWorks 79632 is made for Class III and IV hitches with either 2" or 2.5" receivers that accept a 5/8" diameter pin and need up to a 3-1/4" active span. Some adjustable channel-style hitches and specific branded kits are incompatible, so measuring is recommended before buying.

• Pin diameter: 5/8" (standard for many trailer locks)
• Maximum active length: 3-1/4" to span larger hitch openings
• Does NOT fit CURT channel-style adjustable hitches (models 45900–45902) or Andersen Rapid Hitch/FASTWAY adjustable hitches
• Always measure receiver and hitch tube dimensions before purchase

How secure and weather-resistant are these locking pins?

Each pin uses a tubular keyed lock with a watertight dust cap to protect the mechanism from corrosion and debris. The design combines a mechanical key lock and a separate spring clip for secondary retention, giving redundancy in case one method fails or is removed.

• Tubular push-and-turn lock with 4 identical keys included
• Watertight rubber dust cap shields the lock barrel
• Spring clip (cotter pin) included for extra safety and as a backup
• Rubber O-rings minimize noise and stabilize the pin inside the tube

How easy is installation and everyday use?

Installation is simple: slide the pin through the receiver and hitch, insert the spring clip if desired, then lock with the tubular key using a quick 1/4-turn and push action. The keyed-alike set means both locks operate with the same key set, reducing fumbling when hitching multiple trailers or accessories.

• Push-lock design: efficient 1/4-turn locking action
• Four tubular keys included for convenience and spares
• O-rings can be added or removed to fine-tune fit and eliminate play
• Can be used with or without the lock mechanism by relying on the included spring clip

What should I know about ordering keyed-alike quantities?

This listing ships two locks keyed alike with four keys total. If you need a different keyed-alike quantity, TowWorks offers adjacent SKUs to combine or expand a matched key set. Contact the seller with combined orders to coordinate larger keyed-alike runs.

• 79632 contains 2 keyed-alike locks and 4 keys
• Choose 79633 for three locks keyed alike, 79634 for four
• Combine SKUs and provide quantities to obtain more locks keyed alike
• Confirm key matching requests with the seller when ordering multiple packs

Who is this for? The TowWorks 79632 is best suited for trailer owners, tow operators, and outdoor gear haulers who need a longer-than-standard hitch pin for secure towing connections. It’s ideal if you want a keyed-alike set for multiple attachments, prefer a simple push-and-turn lock, and need extra protection against rattling and weather intrusion. If your hitch is an adjustable channel style or a specified incompatible model, verify fit or choose a different locking solution.
