Struts consist of two telescopic aluminium tubes, outer tube and an inner tube, which can be locked together at various lengths using the side locking bolt and clamp washer. The inner tube is attached to a spring-loaded, black knurled adjustment knob. The adjustment knob mates with the threaded rod in a manner such that the rod translates relative to the inner tube when the knob is rotated. This will provide gradual changes of overall strut length in 0.5mm increments. A reference arrow with plus sign located on the base of the adjustment knob indicates the direction of turning to perform strut elongation - distraction. Each strut has two special joints and one at the base of the outer tube and the other at the end of the threaded rod. Each joint has a mounting stud, which can be inserted into the mounting holes on the ring tabs and held in place by the locking screw. The rapid adjustment of the strut length is achieved by untightening the side locking bolt, sliding the inner tube relative to the outer tube to the desired length. The rapid adjustment is indicated by the inner tube scale in 1mm increments relative to the orange line mark on the outer tube. The gradual adjustment is achieved by pulling and rotating the adjustment knob resulting in a noticeable detect click every 0.5mm of adjustment. Gradual adjustment is indicated by the scale relative to the green line mark.
