Will fit most models of door openers including our line of Door Demons. The ARN-AD06 drive bit has a total length of 6″. The width goes from 1″ to 1 1/2″ at a depth of 4″. This is important as many cars only allow a 4″ insertion. This bit has retaining holes on both axes to accommodate all makes of door openers that use the 1 1/2″ square drive.

Capstan Sockets
Price (ea): $238
Part #: ARN-0072
Our replacement capstan socket has a square drive hole perfect for all types of door openers, not only the Door Demon®. The capstan socket is used when the square drive on the railcar is worn to the point at which a square tool will no longer open the door. The socket slides over the capstan and is pinned in place with a 1-inch pin to transfer the opening torque. The over-sized tube design and square drive hole make the socket usable on almost any door and opener combination on the market.
Pressure Tester Kit
Price (ea): $180
Part #: ARN-0273
The Pressure Tester Kit will allow you to easily check the pressure of your Door Demon railcar opener. This is important when diagnosing performance issues or setting pressure after replacing key hydraulic components such as the hydraulic pump. The kit comes completely assembled and is designed to easily plumb up to existing Door Demon fittings and hoses.
