TowWorks 5/8 in Extra Long Trailer Hitch Lock 4-1/2 in Span - 3-Pack

In this review the TowWorks 79833 keyed alike hitch lock is judged on fit, durability and everyday convenience. It is aimed at trailer owners who use adjustable hitches and 3 in receivers and need a long locking pin that reaches across wider adjustable channels. The single biggest reason to buy is the extra long 5/8 in diameter pin with a 4-1/2 in active span, which solves fit problems that standard pins cannot; the included keyed alike set of three locks and six keys makes it practical for fleets or multiple trailers.

Key Features

• Extra long pin: The 5/8 in diameter pin with a 4-1/2 in active span fits most adjustable hitches and 3 in x 3 in receivers for a secure connection.
• Keyed alike convenience: Three locks are supplied keyed alike with six tubular keys so multiple units open with the same key for faster access.
• Push lock design: The 1/4 turn push lock is simple to operate and the watertight rubber dust cap helps protect the locking mechanism from corrosion.
• Spring clip backup: A separate spring clip (cotter pin) is included so the hitch can be retained quickly without engaging the lock, adding convenience and a mechanical backup.
• Rattle reduction: Rubber O rings are supplied to reduce vibration noise and steady the pin inside different receiver tube sizes.

Who It's For

The TowWorks 79833 is best for trailer owners who use adjustable channel style hitches, including many CURT channel adjustable hitches and pintle hook mounts, and who need an extra long locking pin rather than a standard short pin. It is also a good option for small fleets or users with multiple trailers who prefer three units that are keyed alike for convenience.

Those who use FASTWAY adjustable hitches should look elsewhere because this model does not fit that brand. Buyers who require a different keyed quantity should consider other SKU options or combining packages to achieve the desired number of keyed alike locks.

Pros & Cons

Pros

• Extra long span fits many adjustable hitches and 3 in receivers that standard pins cannot reach.

• Rubber O rings and a dust cap reduce rattle and protect the lock from dirt and moisture.

Cons

• Does not fit FASTWAY adjustable hitches, so measurements must be checked before purchase.
