Penninger Radio single-piece slit bushings are used to join and mate different diameter mast poles. Our slit bushings are from 6061-T6 aircraft grade aluminum. The “slit” is cut along the entire length on one side of the bushing tube. This product is the most cost effective form to join different diameter size tubes and is also compact and lightweight, while providing a high load carrying capacity.
We sell a complete line of slit bushings with a range of: 1.25”-2.5” outer diameters, 1”-2.25” inner diameters, and lengths from 1.5 to 12 inches with custom lengths well over 12 inches. All split bushings have three measurements: outer diameter (OD), inner diameter (ID) and Length. A MC-xxx mast clamp is also required (not included)
