Review on 🚗 Enhance Car Jack Safety with Byenins Large Slotted Universal Magnetic Jack Pad Weld Frame Rail Adapter (Red) - Suitable for All Car Models by Josh Reynolds

Moves or slides on a jack. If your jack is the perfect size for the hockey puck disc and rubber insert, no problem. But if you are using a larger jack for this item it would help to have something on the base to hold it in place. Be it a rubber base or just spikes to hold the jack and washer. Rolled off the jack and the car overturned. The scratched car is pretty good, luckily I wasn't impressed.
