DoorKing unveils slide gate operator

DoorKing has introduced its model 9210 Maximum Security slide gate operator, designed for gates up to 100 feet long and weighing up to 3000 lbs. Gate speed can be set from one-half to two feet per second with a slow start / slow stop operating mode. An anti-tailgating and adjustable mid-stop function improves overall gate security, and a warn-before-operate feature activates an alarm two-to-three seconds prior to gate movement.
