Parking arms are made to contain and direct traffic as well as verify vehicle entry. The arm goes up and down quickly hence their popularity in airports, malls, country clubs and other parking structures. In this category we feature both AC and DC barrier arms. All models are made to last the continuous and rigorous open and close cycles these type of openers require. Barrier arms can be installed as a stand alone machine, work with a ticket spitters, radio transmitter, card readers or telephone entry systems. For safety you will need to add underground safety devices (loops) and/or photo-eyes to make sure that the arm comes down after (not during) each passing car.
