Before connecting a residential opener, why must the sectional garage door be properly reinforced at the top section and balanced by the springs?

The opener is designed to lift the full dead weight of an unbalanced door and needs no reinforcement UL 325 / manufacturer instructions require the door to be balanced so the opener is not the lifting device, and the top section must be reinforced where the operator arm attaches Reinforcement is required only on rolling steel fire doors Balance only matters for manual doors; openers automatically correct a broken spring

Correct Answer:

UL 325 / manufacturer instructions require the door to be balanced so the opener is not the lifting device, and the top section must be reinforced where the operator arm attaches
