Gear Placements – Hexes and Tri Cams

The judgement we need to select a placements for Hexes and Tri cams is very similar to selecting a nut placement. First off is the rock secure than then you need to look at how well the device sits in the shape of crack.

How they are placed is slightly different, as both Hexes and Tri-cams can be placed as passive nuts, however they are designed to cam into placement and become more secure the greater the load placed on them. It is also important to seat them in the placement by applying a shock load by jerking down on the tape.
