Hopper Gate Opener Accessories
Drive Bits
Price (ea): $176

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.

We can manufacture a custom length shaft for your Door Demon®. Standard lengths of 26″ and 36″ are $320. Any custom length (less than 26″ or more than 36″) are $400. The maximum length we recommend is 48 inches (4 feet).
If you need a custom-length shaft, use the contact us form and indicate (in the comments field) the length you require. See above graphic for instruction on how to ascertain the shaft length you require or call us today.
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.
Protective Cover
Price (ea): $75
Part #: ARN-0226
Our all-weather Door Demon® cover helps protect your hopper gate opener from environmental damage while the unit is not in use. 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).
