Jiggers Are Compact 4:1 Pulley Systems and are The Rigger’s Future

Generally, these beauties are considered pre-rigged pulley systems used mainly for hauling, but can be very important in lowering heavy loads as well. The advantage of these systems is in their rapid deployment, and straightforward operation without advanced levels of training or expertise. They are low maintenance and high yield work horses and have been …

Building Anchors with Spring Loaded Cams- Pull Test Using Metolius Camming Units

Building Anchors with Spring Loaded Cams Pull Test Using Metolius Camming Units So we did some back yard testing and while what we found wasn’t particularly astonishing, it was never the less, very interesting. We purposely used some marginal placements with our Metolius camming units.  Some more marginal than others.  We found a range from …
