Perforated / Slotted angles


Perforated / slotted steel anglesSlotted angles are 10 ft. (3 m) long metal strips used to secure the horizontal tracks and garage door opener to the ceiling. Their triangular shape provides greater strength.

To avoid the excessive transfer of noise caused by the vibrations of the opener and the movement of the door, it is advised to place a ¼” (6 mm) rubber pad between the slotted angle and the roof truss.
