We carry standard chain-drive and belt-drive opener units, along with the rail sections, trolleys, and safety sensor kits that cover most residential installs. What we don't stock is anything built for the oldest or newest extremes of a garage - a 1960s screw-drive replacement or a high-end smart opener tied to a specific home automation system is a special order, and we'll tell you that on the phone rather than let you find out when the truck shows up short.
Given that University Park's housing runs mid-1980s on average, most jobs here call for a standard 1/2 horsepower belt-drive unit, which is what we keep on the truck in the most volume. If your garage has been updated with an insulated steel door heavier than the original, we'll check the spring balance before we hang the opener - an opener fighting an unbalanced door burns out early no matter how good the unit is.
