TowWorks 79832 Keyed Alike 5/8 in Extra Long Trailer Hitch Lock

In this review of the TowWorks 79832 keyed alike trailer hitch lock, the bottom line is simple: it is for owners of adjustable hitches and 3 in x 3 in receivers who need a long, reliable locking pin that reduces rattle and resists moisture. The reviewer found the extra long 5/8 in pin with a 4-1/2 in active span to be the single biggest reason to buy, because it fits many channel-style adjustable hitches and adjustable pintle hooks where standard pins come up short. It is a straightforward, durable solution for securing trailers and adjustable mounts.

Key Features

• Extra long 5/8 in pin: The extended 4-1/2 in active length fits most adjustable hitches and 3 in x 3 in receivers that require a longer pin span.
• Keyed alike convenience: Two locks arrive keyed alike with four tubular keys, so multiple locks unlock with the same key for easier operation.
• Push lock and 1/4 turn action: The push lock design with a 1/4 turn makes locking and unlocking quick and simple under field conditions.
• Spring clip backup: The included spring clip (cotter pin) provides an extra layer of safety and a quick-change option without the lock body.
• Rubber O rings and cap: O rings reduce rattle and a watertight dust rubber cap helps protect the locking mechanism from corrosion and dirt.

Who It's For

The TowWorks 79832 is best for DIYers, fleet operators, and recreational users who regularly use adjustable channel-style hitches or adjustable pintle hooks and need a longer locking pin than standard pins provide. It suits anyone who values keyed alike convenience for multiple trailer connections and wants a rattle-reduced, weather-protected locking pin.

It is not appropriate for owners of certain adjustable hitch brands that use a different mounting system; specifically, this lock does not fit FASTWAY adjustable hitches. Buyers should verify hitch dimensions before purchase rather than assume universal fit.
