Prime-Line 25 in. 110 lb. Garage Door Extension Spring with Cable

The Prime-Line Garage Door Extension Spring provides reliable lifting power for residential sectional, overhead, and wood garage doors. Rated for 10,000 cycles, this heavy-duty spring is constructed from durable carbon steel with double loop ends engineered to withstand daily operation and long-term tension. For enhanced safety during operation, the included galvanized aircraft cable runs directly through the center of the spring to prevent personal injury or property damage in the event of spring breakage. Designed to replace most standard residential spring configurations on garage doors up to seven feet tall, two springs will properly counterbalance and lift a door weighing up to 110 lb.
