Welcome to our store! 【2PCS Spring Rollers with Side Parking Brake】: Adjustable spring support, spring type maximum vertical stroke of 1-3/4". Automatically adjust the height (0-5.08cm) on uneven ground to prevent the gate from opening and closing freely when the gate drops. 【Heavy load】: The whole roller is made of high quality rubber material and metal structure, combined with double ball axles which provide double load. The maximum load capacity of each door roller is 220 pounds to prevent the door from sagging. 【Flexible rotation】: Double ball axles and 360° rotation in all directions, with labor-saving design, easy to move and roll, easy to open and close and effortless. 【Built-in Spring】: This is a newly designed door roller which is different from the traditional door theory.
