TOWSWELL Trailer Hitch Pin Locks for 2" Receiver — 5/8" Pin, 2-Pack, Rust-Resistant Push-to-Lock

TOWSWELL 5/8" trailer hitch pin locks secure 2" (Class III/IV) receivers with a rust-resistant steel pin and push-to-lock convenience in a two-pack.

These receiver hitch locks are designed to keep your trailer, bike rack, or accessory firmly attached to your tow vehicle without the bulk of heavy chains or complex hardware. Constructed from hardened steel with a black protective finish and a waterproof rubber key cap, the locks resist corrosion and dirt so they stay functional through wet, snowy, or dusty conditions. Each lock uses a 5/8" diameter pin with a 2-1/2" span, fits standard 2" receiver tubes, and comes as a set of two locks with four keys for paired use or sharing between vehicles.

How do these hitch locks fit my trailer setup?

The pins are sized for 2" trailer receivers commonly found on Class III and IV hitches. The 5/8" diameter and 2-1/2" length span fit typical hitch pin hole spacing, providing a secure match without modification. Check your receiver’s pin diameter and hole spacing to confirm compatibility before purchase.

• Designed for 2" receiver tubes — common on Class III/IV hitches
• 5/8" locking pin diameter, 2-1/2" span for standard fit
• Ideal for trailers, RVs, bike racks, hitch carriers, and more

What makes the locks durable and weatherproof?

The main body and pin use high-strength steel with a black protective coating to resist bending and surface corrosion. A rubberized key-slot cap seals the cylinder to keep out moisture, dirt, and sand, prolonging smooth operation. The push-to-lock mechanism avoids exposed springs or latches that commonly fail under road grime.

• Hardened steel construction for bending resistance
• Black corrosion-resistant finish for outdoor use
• Rubber key cap to block water and dust from the keyway

How easy is installation and daily use?

Installation is quick: slide the pin through the hitch receiver and accessory shank, press until you hear a click, and the lock secures automatically. Unlocking requires only a quarter-turn of the key to release the spring-loaded pin, which pops up for simple removal. This straightforward action saves time when loading or swapping gear.

• Push-to-lock — locks with one firm push and audible click
• Quarter-turn key operation for fast unlocking
• Spring-assisted pop-up pin for easy removal after unlocking

What do I get in the package and how are the keys managed?

This listing includes two independent 5/8" hitch pin locks and four separate keys — each lock has two matching keys. Locks are keyed differently from one another (KD), so one key will not open the other lock; carry spares or label keys for convenience. The set allows locking both a trailer and accessory or keeping a backup key safe.

• 2 x 5/8" receiver hitch pin locks and 4 x keys included
• Each lock comes with two identical keys for that lock
• Locks are keyed differently from each other (not keyed alike)

Who is this for: Owners of trucks, SUVs, RVs, or cars with 2" receivers who want a low-profile, durable locking solution for trailers, bike racks, cargo carriers, or other hitch-mounted accessories. It’s well suited for weekend haulers, outdoor enthusiasts, and fleet vehicles that need reliable theft deterrence and weatherproof performance without complex installation.
