- SKU: 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.
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.
Wheel locks are usually replaced because of corrosion, seized lock cylinders, bent clamping arms, or lost keys rather than normal towing wear alone.
The product image shows the TWL100 installed on the wheel of a side-by-side, which is a strong real-world example of how this lock fits small recreational and utility equipment when wheel size and clearance are compatible.
