12" SS Support Arm

This 12" stainless steel support arm is sold individually, but must be used in pairs to prevent glazing damage to the window. Pushing the vent open to the full extent of the arms automatically engages the mechanism; for safety, the vent should always be secured in the open position by engaging the lock lever on each arm. To reclose the vent, rotate both locking levers to the unlocked position and push the vent outward to disengage the latches, ensuring even pressure is applied so that both arms release simultaneously.
