It is essential to factor in safety when planning your overhead rolling security grille. We have options that are reliable, secure, and ADA-compliant.
This interior-wall-mounted release is easily accessible and meets ADA requirements. When the pull handle is released, it will disengage the motor from the counterbalance barrel assembly and the door can then be operated manually. Returning the handle resets the grille/closure to normal operation.
This compact design is the standard for the retail industry. Constant contact provides secure operation for your rolling grille. (NEMA 1)
Reverse Sensing Edge
Recommended for motor operated rolling products. Mounted on the bottom bar, the sensing edge will stop and reverse the grille if an obstruction is encountered while it is closing.
