Lock Technology's LT465 12mm and 14mm Wheel Hanger Guides slide into wheel lugnut holes without using threads saving the technician time, because they involve no turning the wheel guide to install and remove. Wheel hanger guides support wheel/tire so the technician can easily thread lugnut bolts into the brake rotor and avoid dropping the tire or having the outside section of the rim hit the floor and scratch. Made of durable bulletproof polycarbonate plastic. Works on Mercedes, Audi, BMW, Mini Cooper, SAAB and Volvo vehicles. Each kit includes one 12mm and one 14mm wheel hanger guide.
