Screw-on felt protects the floor from scratch/dent. Only downside is stamped metal not deburred from the factory.

It takes the longest to apply due to pre drilling required, but worth the effort. Easy install with a drill. Just take some time to pull them off before installing.

Unless you tap it perfect every time (big or small taps) they bend and are useless. Attempted to replace similar product with previous nail holes and still terrible. Need to return.

The pads ruined other floors as well. Adhesion is weak. What a waste of money.
