Soft Durometer Bumpers have been specifically engineered to provide the quietest closure available for any cabinet door, drawer or enclosure. The Soft Durometer bumpers use a device called "flexible softness" which absorbs the physical force of the close by more than half. A very soft polyurethane material and varying unique designs are employed to achieve this impressive result. Bumpers help preserve the life of hardware by cushioning the impact and preventing loud slamming. Easy application: Simply peel the bumper from the liner and apply to where protection is needed.
