MICROgrip 3/8" Solid Aluminum Black Rod is designed for the 3/8" Grip Gear. The 3/8" MICROgrip Rods come in two different terminating ends, 3/8" Male and 1/4-20" female and both feature a smooth flat black anodized finish. The MICROgrip rods and heads can be used for camera rigs whenever a smaller lightweight rig is preferred. They are also ideal for table top photography. 3/8" to 3/8" Coupler: if connecting two 3/8" male end rods together, you will need a 3/8" to 3/8" coupler.
