COA

COA parts at Protec Controls are mostly air switch and hose items for door edges and driveway treadles. You will find 100 foot rolls of treadle hose and gummed door edge hose, normally open and normally closed air switches, hose anchors, splitters and clamps, plus a warning bell, a solar charging kit and two gate locks.

Match switch contact type to the control input. See overhead door parts.
