Trimax Ultra-Max Adjustable Wheel Lock for 10" to 18" Wheels with Steel Lug Nut Protector (TWL100)
Heavy-duty adjustable wheel lock for trailers, side-by-sides, and other equipment. The TWL100 clamps tightly to the wheel and uses a steel lug nut protector to help prevent tire removal and theft.
R&P Knowledge Hub
Compatibility: Opens to 14" and fits nearly all 10" to 18" wheels across a broad range of trailer, vehicle, and equipment applications.
Vehicle / System Fit: Designed for trailers, cars, UTVs, trucks, construction equipment, boats, and 4x4s using compatible wheel size and clearance.
Installation Notes: Position the lock over the wheel, adjust for a tight fit, and verify the steel protector is covering the lug nut area correctly before locking. Tools and instructions are included.
Performance Insight: This design does more than block wheel rotation. The steel lug nut protector adds another layer of security by making it harder to access lug hardware and remove the wheel itself.
R&P Service Insight
Wheel locks are usually replaced because of corrosion, seized lock cylinders, bent clamping arms, or lost keys rather than normal towing wear alone.
- Exposure: Outdoor storage, rain, and road grime can affect moving parts and the lock core over time
- Handling Damage: Forced removal or improper fitment can bend the arm or protector plate
- Security Wear: Frequent locking cycles can gradually wear keys and cylinders, especially in harsh environments
