Describe package contents: Color: Black. Quantity: 4 V-shaped; Length: 63mm Height: 45mm Width: 50mm. BEST CHOICE FOR CARS: Jack adapters are excellent protection to prevent your frame rails (especially pinch welds) from bending or scratching when used with side stands. Rubber pads provide extra support and reduce slipping when lifting the car. UNIVERSAL FOR MOST CARS: Made of heavy-duty construction and heavy-duty rubber, suitable for 3-5 ton floors, fits most jacks. Check the dimensions and make sure they fit your jack and vehicle. Reminder: The durable rubber material can last a long time, while the soft rubber yoga surface will not rub off. The chassis will not be scratched. Due to the robust rubber material, it smells a little of rubber. Please place it in a ventilated room for a few days. Dimensions: 50 x 63 x 44 mm Important points: 1.
