It is necessary to routinely lubricate the hinges on all Tunnel Ventilation Doors. We recommend using ZEP Z-Works High-Pressure Lubricant, and we sell it by the bottle or the case. Failure to lubricate the hinges could void the warranty.

Our durable tunnel ventilation doors now come with a rigid vinyl meeting rail to prevent sweating. When installing the doors, it is recommended to screw the meeting rail to the doors to prevent slippage.
