Arkon Security Hardware for 38mm Ball Compatible Robust Shaft Arms

Arkon's SPRM38SHKIT provides the hardware needed to replace the knob on one of Arkon's 38mm ball compatible Robust Shaft Arms in order to deter theft. The security hardware kit includes a 5/16 inch - 18 acorn nut, a 5/16 inch - 18 x 2 Torx head screw, and a 3/16 inch x 1 inch Torx bit. These replace the knob and screw currently found on all 38mm ball compatible Robust Shaft Arms.
