The Trimax Ultra-Max wheel lock covers your lug nuts with a heavy steel disc, making it much harder for someone to pull a wheel while your RV or trailer is parked. It adjusts to fit many different tire and wheel sizes.
An adjusting arm lets you snug the disc down closer to the lug nuts on deeper wheels for a tighter fit. It comes with three keys and is available keyed alike if you're locking down multiple wheels, and it's backed by Trimax's lifetime warranty.
A straightforward layer of theft deterrence for trailers left parked at storage lots or campsites.
