About Proven Industries
Proven Industries describes itself as a family owned and operated maker of trailer and security locks. Its own story says the business began after the family's trailer was stolen with about $40,000 of equipment inside, secured only by a low-grade coupler lock. The company says it manufactures its lock bodies in the USA and puts an average of 200 hours of research and development into each product line.
The range centers on trailer security: coupler locks for 2 inch and 2 5/16 inch couplers, gooseneck and 5th wheel locks, puck locks and hasps, plus hitches, hitch accessories and job site boxes. On RevRated, the WL-200 J-style wheel lock is one of the top picks in our trailer wheel lock reviews, where it stands apart from the boot clamps and chock locks.

Why we recognized Proven Industries
The RevRated Top Brand recognition isn't paid for and can't be applied for. We award it to the brands whose products consistently stand out in our category roundups. Proven Industries earned it on the strength of the products below, evaluated the same way every product on this site is: checked against the specs, fitment data and verified buyer reviews, and judged on merit.
Proven Industries products we rated highly
Proven Industries WL-200 Wheel Lock (Long Arm)
A J-style lock: a hardened steel arm with a black powder coat hooks behind the wheel and locks with a puck lock, so there is no exposed shackle for bolt cutters to grip. The key system is built to resist picking and copying. It fits any lug pattern on 15 and 16 inch wheels, single or tandem axle. Fit is narrow by design: it suits only factory steel wheels on leaf-spring trailers without brakes, so a braked trailer or one with aluminum wheels needs a different lock.

- The WL-200 takes a different approach from the boot clamps and lug-nut covers in our reviews, and we judged it the most purpose-built option for the trailers it fits.
- The company lists a lifetime warranty across its lock range.
- A keyed-alike option lets a buyer open several Proven locks with one key.
- The product line grew out of a real trailer theft, which shows in a range built almost entirely around locking trailers down.
