Hillman 25 in. x 150 lb. Extension Spring w/Safety Cables, Red

Hillman 25 in. x 150 lb. Extension Spring w/Safety Cables, Red is designed to provide reliable support for your garage door by counterbalancing its weight as it opens and closes. These extension springs are mounted along the sides of the garage door or above the horizontal tracks and stretch and contract during door operation. Typically, residential garage doors use two extension springs, one on each side, while commercial doors may require multiple springs on each side for added support. This package includes detailed instructions, mounting hardware, and important warning and safety information to ensure proper installation and safe use. Please note that incorrect installation or improper door positioning can result in serious injury or death, so it is essential to follow the enclosed guidelines carefully. Model Number:
