The D 1802 sliding door bumper is an essential hardware accessory for homes with sliding doors. Fasteners are included. As a safe buffer, it prevents direct impact between the door and the frame, effectively preventing scratches, dents, and structural damage to patio doors, glass doors, and shower doors. This door bumper is designed to prevent doors from slamming shut, creating a quiet and comfortable home environment while extending the lifespan of the sliding door and frame. The rubber door bumper is fixed to the appropriate door frame to prevent violent door impacts and is an ideal replacement part. Easy to install, compatible with most standard sliding doors, it provides stable cushioning and impact protection. It can also be installed on other doors as needed to prevent violent door impacts. Please refer to the dimensions in the illustration and compare them with your needs before ordering.
