  • Patent number: 4095641
    Abstract: An attachment for use with an overhead door having limited head room. The door is made of hingedly connected sections and movable between a closed and an open position on a track. The attachment comprises a first member adapted to be attached to the top section of the door. A second member is pivotally connected to the first member. Track engagement means are attached to the second member and abutment means are positioned on the second member to abut a stop positioned on the exterior of the track when the door is in the closed position. Abutment of the abutment means on the stop acts to stop movement of the second member in the track at a point just prior to the door reaching the closed position.
