The Volt Dock Tool Caddie for Tiffen size arm posts is a great place to store an arm post, a low mode bracket and pin, block battery cable, allen keys, and more. It holds 1 arm post, 1 low mode bracket with pin holes, block battery cable, and has 4 holes for allen keys. It can be printed for either side of the dock, but is only compatible with the intended side.
 
IMPORTANT: To select correct orientation, look at the fork of your dock (your sled should be in your face if docked). Left is to your left, etc. Main tool caddie MUST be mounted opposite your arm hanger. If you have any questions, please reach out.
