It measures 3.5\" overall and 2.75\" from ball center to ball center. Tackform makes shorter arms, but the dual-socket layout here gives the widest range of articulation for placing a device exactly where you want it.\u003c\/p\u003e\u003cp\u003eIt is part of Tackform's 20 Series, built around the 20mm ball and socket. It works with other 20mm products, and Tackform says its parts are tested for load capacity with a safety factor that other makers do not guarantee. A black knob is included, and the arm is compatible with Tackform's anodized billet aluminum DuraLock knobs if you want to match your vehicle.\u003c\/p\u003e\u003cp\u003eChoose your accent kit color from the options on the listing: black, blue, green, orange, pink, purple, red or yellow.\u003c\/p\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eUniversal, for 20mm ball-and-socket parts.
