Big RED 2 Pack Hitch Lock Pin is a heavy‑duty 5/8" diameter locking pin designed to secure 2" and 2.5" trailer receivers, providing theft deterrence and weather resistance for trailers, boats, RVs, cars, and trucks.

This two‑pack of keyed hitch pins from Big RED combines hardened steel construction, chrome plating, and an easy push‑in locking head so you can quickly secure your trailer or accessory.

A rubber cover and zinc alloy keyhole help keep moisture and grit away from the lock mechanism for reliable operation in varied conditions.

How do these hitch locks attach and lock?

Operation is straightforward: press the keyed head to insert the pin through the receiver; you’ll hear a click when the head engages. To remove, insert the key and turn a quarter turn to release the locking head, which pops up automatically for easy retrieval.

• Push‑in, keyless push action to set the lock quickly
• Turn key 90° to unlock and release the pin
• 360° rotating head for flexible alignment in tight spaces
• Two matching keyed pins included for dual trailer or backup use

Will these pins fit my trailer receiver and accessories?

Each Big RED pin is 5/8" in diameter with a 3.54" effective length, sized for standard 2" and 2.5" receiver tubes commonly found on Class III and IV hitches. They work for fixed‑position receivers, stabilizer bars, and many hitch‑mounted accessories where a standard hitch pin is used.

• Designed for 2" and 2.5" receiver openings
• 3.54" effective shank length for common hitch widths

How durable and weather‑resistant are these locking pins?

Big RED constructs the pins from hardened steel and finishes them with chrome plating to resist bending, rust, and corrosion in outdoor use. The keyed slot is protected by an all‑weather rubber cover and a zinc alloy keyhole for extra anti‑corrosion protection, extending service life even in coastal or rainy environments.

• Hardened steel core reduces bending and tampering risk
• Chrome finish helps block rust and surface corrosion
• Rubber key slot cover keeps moisture and dirt out
• Zinc alloy keyhole improves anti‑theft durability
