We sell solid and hollow shafts as well as couplers for torsion spring systems. The solid shaft (pictured to the right of the hollow shaft) comes in 1" and 1-1/4" diameters and is equipped with a fully keyed slot. Key stock should be used when connecting couplers and cable drums to the shaft. When joining two shafts together, you will need to use a coupler. Adjustable cast iron couplers, pictured back center, can make door repair much easier than if you use a non-adjustable coupler.
Hollow shafts are also available in 11 and 14 gauge for residential and lighter commercial applications.
IMPORTANT NOTE REGARDING LOCAL PICKUPS: DDM is considered a life-sustaining company because we are an internet retail company that provides essential products. Due to the recent outbreak of Coronavirus, however, we are changing our local order pickup policy at our West Chicago location. To pick up an order you will need to order first. The quickest way is to order in advance through our online shopping cart. There you can select the local pickup option. Or, you can call 630-293-1337 for assistance, to confirm availability of parts, and to place your order. Once ordered, your parts will be available for pickup in the lobby of our north side front entrance. Longer items will be picked up on the south side loading dock. Please honor the six foot social distancing rule. Thank you for your patience and understanding as we all navigate this challenge together. More information is available on our blog titled DDM Adjusts to the COVID-19 Coronavirus.
