The 1.5INV Series magnetic adapters provide an SMR nest which fits on any of our Invar System bars. With both English and metric versions available, the centerpoint of a 1.5" diameter SMR may be held either 1.000" or 25mm away from the interface surface between the adapter and the Invar bar. The SMR seats on a 3-point conical land and is held in place by a strong magnet. The discontinuous three point mounting system gives extra room for the SMR to be tilted further away from the bar's main axis, giving additional mounting flexibility. The adapter's threaded mount is 3/8"-24 for compatibility with our Invar system.
