Definition
The traditional way opener strength is labeled — 1/2 HP, 3/4 HP, and up. Modern DC openers often use 'comparable' ratings like HPc or HPs because their motors are measured differently, so treat the number as a sizing guide rather than a lab figure. A 1/2 HP-class unit handles most single steel doors; heavy, insulated, oversized, or wood doors deserve 3/4 HP or more. Remember the spring does the lifting — an opener compensating for tired springs wears out early no matter its rating.
