Will fit most models of door openers including our line of Door Demons. The 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(s)
Door Demon® Cover
Pin Socket(s)
Price (ea): $238.00
Part #: DD-Socket

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 oversized tube design and square drive hole make the socket useable on almost any door and opener combination on the market.

It is made of durable canvas and features reinforced seams for added protection. This cover is fit for use with any of our two wheeled hopper gate openers (with or without the side-shifting wheels option).
