TRI CAMS are versatile, lightweight and compact. They work where other nutting is next to impossible, like in narrow solution pockets or big huecos. In their simplest mode, TRI-CAMS can be placed like any other standard wedge. To take advantage of a TRI-CAMS full potential in parallel or flared cracks and solution pockets, position the attached sling down between the camming rails, insert into the rock and then give the sling a good jerk to "set" the nut. To add security to the placement you can locate the fulcrum point in a small depression or place in opposition with another nut.
The EVO's wider tapered head allows for a 3rd cam placement making it even more veritile and the stiffer sling makes for easy one handed placements. Made in Italy.
