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″.

Capstan Socket - Hopper Gate Opener Accessory
Capstan Sockets

Part #: ARN-0072
Price (ea): $238

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.
