"...when I fell the cam was at or less than a foot below my feet. The placement was in a pocket where the crack above and below the placement tapered out. It was cammed to the middle lobe ... The stem was angled down about 45 to 60 degrees"

Michael Lane from Omega Pacific responded: "Link Cams are specialty pieces ... [and are] vulnerable to damage and failure if subjected to torsional loading that requires the relationship of the head/axle and the rock to change much during a fall, especially if the placement is bottoming or loads the lower-end linkages to be stressed over any kind of edge or intrusion ... the fact that their lobes consist of hinged components when other cams are made of a single piece of material made this [torsional/bending loading issue is] an obvious characteristic from the start."
Furthermore he reports that Omega Pacific are taking action in response:
"1) We're looking at new link designs that strengthen the hinges to make them stronger.
2) We'll be rewriting our literature to emphasize proper placement of Link Cams with a clear warning about the potential consequences of placing them in ways they could be subject to damage."
