BulletProof Hitches Black Ops Extreme Trailer Lock Set

The BulletProof Hitches Black Ops Extreme Trailer Lock Set is a three-piece security bundle for tow rigs, covering the receiver tube, the coupler, and the trailer latch in a single purchase. The set includes a 5/8" locking pin, an Extreme Duty Coupler Lock, and a Trailer Latch Lock, all sharing a common key (six keys are included). The pin fits 2", 2.5", and 3" receivers; the coupler lock fits 1-7/8", 2", and 2-5/16" couplers.

Three Lock Points, One Key

Trailer theft typically exploits whichever connection point is left unsecured. The Black Ops set addresses the receiver tube, the coupler, and the trailer latch simultaneously, so no single point is left exposed. Because all three locks share the same key, there is no separate key ring to manage at the campsite or trailhead.

Built to Resist Picking and Corrosion

The 5/8" Black Ops Locking Pin uses stainless steel internals and a pick-resistant locking mechanism. A heavy-duty rubber cap covers the keyhole on both the locking pin and the Extreme Duty Coupler Lock, blocking dirt, moisture, and road debris from reaching the mechanism. All three locking products are treated with an aircraft-grade lubricant to extend service life in outdoor conditions.

Universal Receiver Fit with Anti-Rattle Spacers

The locking pin's 4" of usable length and 5/8" diameter cover every standard receiver size. Two anti-rattle spacers are included with the pin: one sized for 2" receivers and one for 2.5", so the pin seats snugly without movement or noise while towing. The Extreme Duty Coupler Lock's 1" solid steel bar spans the three most common coupler sizes without an adapter.

Specifications

Who This Is For and Isn't

The Black Ops Extreme Trailer Lock Set suits any tow-vehicle owner who wants simultaneous receiver, coupler, and latch security in one purchase. The locking pin's universal sizing covers 2", 2.5", and 3" receivers, and the coupler lock covers the three most common ball sizes, so the set works across a wide range of trucks, SUVs, and trailers without additional adapters.

The Trailer Latch Lock is compatible with most coupler types but not all; buyers with uncommon or proprietary coupler designs should verify compatibility before purchase. This set does not include a wheel chock, wheel lock, or any other form of trailer immobilization beyond the three locking components listed.

Common Questions

Do all three locks in this set use the same key?

Yes. The BulletProof Black Ops Extreme Trailer Lock Set is keyed alike: the locking pin, the coupler lock, and the trailer latch lock all operate with the same key. Six copies of that key are included in the set.

What receiver sizes does the locking pin fit?

The BulletProof Black Ops Locking Pin is designed for 2", 2.5", and 3" hitch receivers. Its 5/8" diameter and 4" of usable length cover all three sizes. Anti-rattle spacers for 2" and 2.5" receivers are included so the pin seats without movement or noise during towing.

What coupler sizes does the Extreme Duty Coupler Lock fit?

The BulletProof Extreme Duty Coupler Lock fits most 1-7/8", 2", and 2-5/16" trailer couplers. Its 1" solid steel bar spans these three common ball sizes without an adapter. Buyers with non-standard or proprietary coupler designs should confirm compatibility before ordering.

How are the locking mechanisms protected from the elements?

On both the locking pin and the coupler lock, the keyhole is covered by a heavy-duty rubber cap that blocks dirt, moisture, and road debris. All three locking products in the Black Ops Extreme set are also treated with an aircraft-grade lubricant at the factory to extend service life in outdoor and road conditions.

Is there a California Proposition 65 warning for this product?

Yes. California residents should be aware that the BulletProof Black Ops Extreme Trailer Lock Set carries a Proposition 65 warning: this product contains chemicals known to the State of California to cause cancer, birth anomalies, or other reproductive harm.
