Pass Doors

Pass doors are ideal in applications where space is too limited for the installation of a standard entry door. They conserve energy by allowing building access via a smaller opening versus the entire sectional door, this minimizes wear and tear on the door as well saves electric operator cycles. In inclement weather, the heat or cold distribution between inside and outside of the building is minimized, conserving additional energy costs.

Available On 3720, 3722, 3724, 3200 and 3220 insulated models.
Available Colors Pass door frames are available in White or Brown. Other colors are available via custom order with extended lead times. 


Break-away Bottom Sections

Break-away bottom sections will release from the track and swing up to a full 45 degree angle inward or outward, preventing further damage to the door.

Available On 3200, 3220, 3717, 3718, 3720, and 3722 insulated models.



The Safe-T-Stop is a controlled descent sectional door hand hoist with an integral braking system allowing users to operate the door with confidence. Unlike standard chain hoists that could allow the door to move out of control, with the Safe-T-Stop the door only moves when the user is actively pulling the chain reducing the risk of mishandling the door. When the chain is not actively pulled the brake engages keeping the door in place.
