ProLine LST2BK Speaker Stand Clamp

This is a replacement clamp/clutch piece for the ProLine LST2BK speaker stand, which has an outer tube diameter of 38mm (lower part of stand) and an inner tube diameter of 35mm (upper part of stand). There is an M6 nut and bolt that clamp the piece on the outer tube, and an M8 nut and threaded knob that hold the inner tube in place, which is used whenever raising/lowering the stand in normal use.

Compared to the original piece, I thickened up the pieces that retain the nuts, so hopefully this will last longer than the factory part. The same piece broke on both my stands, in the same place around the M8 nut. Since the pin takes the brunt of the shear force imparted by the speaker during use, the clamp doesn't need to be tightened all that much anyway.

Enjoy!
