TOWSWELL Hitch Receiver Pin Lock 5/8in 2-Pack — Keyed, Weather-Resistant for 2in & 2-1/2in Receivers

TOWSWELL Hitch Receiver Pin Lock is a rugged 5/8" locking pin set designed to secure 2" and 2-1/2" Class III/IV hitch receivers on trailers, trucks, cars and boats — supplied as a two-pack with keyed locks.

When you tow, park or leave accessories attached to your vehicle, a dependable hitch lock prevents theft and unwanted removal. This two-pack of TOWSWELL receiver pin locks combines heavy steel construction, a weather-resistant finish and an easy push-to-lock action to hold accessories like bike racks, cargo trays and trailers firmly in place. Each lock ships with two independent keys for straightforward access, and the set fits common 5/8" pin holes with a 4" span to match industry-standard receivers.

How does this lock fit different hitch receivers?

The pin measures 5/8" in diameter and is built to fit both 2" and 2-1/2" receiver tubes typically found on Class III and IV hitches. A 4" span provides the clearance required across most receiver openings and mounted accessories. The rotating head helps line up the lock when inserting into tight receiver spaces.

• 5/8" locking pin diameter → matches standard receiver holes
• 4" span → accommodates common hitch widths and accessories
• Works with Class III and Class IV hitch configurations
• 360° rotating head → easier alignment and installation

Will this lock withstand weather and corrosion?

TOWSWELL designed the pins with a black rust-resistant coating and sealed key caps to defend against moisture and dirt. The steel core resists bending and the protective finish reduces surface rust over time, making the locks suitable for outdoor and marine environments. The rubber key slot cap keeps the keyway cleaner and helps extend service life.

• Black corrosion-resistant coating protects metal surfaces
• All-weather rubber key cap blocks water and debris
• Solid steel construction reduces risk of bending or deformation
• Appropriate for trailers, boats, RVs, and exposed use

How simple is installation and everyday use?

Installation is a one-handed push-to-lock action that clicks into place, so you can secure the hitch in seconds and confirm engagement audibly. Unlocking is done with the supplied keys; each lock includes two independent keys, and keys are not interchangeable between locks to increase security. The rotating head and smooth pin travel reduce hassle when inserting through mismatched holes or accessories.

• Push-to-lock design → audible click confirms secure closure
• Two keys per lock → spare key included for convenience
• Keys unique per lock (KD) → prevents cross-opening
• 360° rotating head → simplifies aligning the pin

Use it to secure trailers, bike racks, hitch cargo carriers, tow bars and other hitch-mounted accessories across trucks, SUVs, cars and boats.
