Abstract
A safety device is provided for an upward acting door supported by a support cable, the door being movable along a pair of parallel tracks between an open position and a closed position. The safety device includes a brake pad mechanism disposed within at least one of the parallel tracks and coupleable to the door, the brake pad mechanism operable between a released position, to enable movement of the door as the door is positioned between the open and closed positions, and a braking position, to resist movement of the door. The support cable is coupled to the release mechanism such that in the event of a loss of tension of the support cable, the release mechanism actuates from the released position to the braking position to resist movement of the door.
