The 3-way armback allows you to make an angled "T" shape connection. It can be used with tubings or with our fabric wires when used with a male cord grip. The armback is compatible with our 3/8" OD tubings with 1/8 IPS threading. The side hole comes in at 45 degrees allowing you to play with new shapes and angles with your fixtures. Any of our male threaded cord grips will also be compatible.
