Do doorway pull up bars damage door frames?

Most leverage mounted pull up bars distribute weight through rubber padded contact points on the door frame, which prevents scuffing and denting when used correctly. However, repeated heavy use can leave marks on painted trim, especially with heavier users. Adding foam pads or microfiber towels between the bar and frame provides extra protection. Telescoping bars that press against the inner door jamb carry a slightly higher risk of chipping paint if they slip.
