1" Bore, Face Tapped Clamping Hub, 1.50" Pattern

This clamping hub is perfect for applications that utilize 1" tubing and demand high holding power. Using large tubing opens up possibilities in your build not otherwise available.  The hub has four 6-32 tapped holes on the Actobotics 1.5" pattern commonly found throughout the build system.    Note, if your project would benefit from a version of this hub that has threaded holes, please check out the 545354.
