Door bumper keeps your main door from swinging too far open and hitting the side of your machine. Not all machines had them but it is a nice touch when you have spent money on the paint job and trim pieces. Will work nicely on Vendorlators like the VMC-33-3D, VMC-81, VMC-88, VMC-110 or any other RC yellow machine that needs one.
Yellow rubber. Mounts to side of machine.
