Review on Prime-Line Products D 1802 Sliding Door Bumper 2-5/8-Inch White Rubber - Pack of 2: Effective Sliding Door Protection by Andrew Grimes

The bumper received the same article but differs from the picture. There is a small recess on the contact surface with the door. This reduces the contact area, which means higher pressure per unit area. This could potentially damage the door if you are not careful. It would make it pointless to have that bumper. It's also a hard plastic, not the same as the original hard but slightly resilient rubber-plastic bumper. BUT the part number is the same, I don't know why.
