Here we have some out of box ex-display HXOCII Open Clamps offered at a great price.
If you want to use your Hexrack with different brands of hardware or you want to heavily customise the design of you rack with specific tubes and angles, you are going to want to use some open clamps.
The open clamp is used to attach tubes with different thickness (diameter 15-34mm, including the hex rack hexagonal tubes) to a hex rack hexagonal tube. Although fine angle adjustment is possible with the 360 degree gear joint, more stable setting can be achieved by limiting the movement only to the vertical direction.
The open clamp comes with the inner sleeve and a fully integrated memory lock which ensures complete lock at any angle.
