Mommy"s Helper Soft Jamb Door Stops This innovative doorstop combines child safety with protection for your doors and walls. Unlike two-piece styles that consist of a spring and small cap, these doorstops offer a safe, one-piece design -- no small parts to pose a choking hazard and no springs to pinch precious fingers. The shock-absorbing design prevents damage to walls and doors. Easy to install, it screws right into the existing hole.
