The HXACII clamp is one of the secret weapons for completely customising your Hexrack. It will secure tubes of different thicknesses (including the Hexrack hexagonal tubes) These clamps can be used to secure tubes positioned far from each other too. Each clamp has a 360 degree gear joint, enabling fine angle adjustment.

In the second picture we have demonstrated the HXACII holding two leg sections together and clamping a cymbal arm from a leg section. The possibilities are never ending with this clamp.
