With the most versatile offering of cams on the planet, Ultralight Power Cams, TCUs, Offsets, Fat Cams and Supercams, why add a single-stem cam to their line? The reason is that there is an infinite number of variables in the climbing environment: hard rock, soft rock, parallel cracks, flared cracks, etc . . . Each individual cam style excels at a certain set of variables. The Fat Cam’s wide lobes greatly improve protection in soft rock while the TCU’s narrow head widths greatly enhance placement versatility. The biggest advantages of the single-stem unit are: they will fit into certain placements better than the U-shaped body and the flexible, single cable reduces leverage to minimize walking in certain placements. Metolius set out to make the finest single-stem unit we possibly could and the Master Cam is the result. The Master Cam combines a nice, flexy cable with an ultra-narrow head for hard aid or free climbing. Since they invented the CNC milled cam-stop, they naturally applied them to Master Cams. They also joined their silky-smooth trigger assembly with an ergonomic thumb piece to provide precise control over placement and retraction. The longer body affords additional reach when top-stepping or stretching for that hard-to-get placement. The Range Finder system also provides critical placement feedback for those who need it. Master Cams are hand-built right here in Metolius' Bend, Oregon shop. Each one is thoroughly inspected and every unit is tested to 5 kN. Master Cams are CE and UIAA certified.

The Master Cams by Metolius are their first single stemmed cam they have made due to all the different styles of cracks you can encounter when climbing. Based on the idea that a single stemmed cam can fit better into awkward cracks and fissures than the U-shaped body and the flexible, single cable reduces leverage to minimize walking in certain funky placements.
The Master Cam offers climbers a narrow head and flexy cable piece that is made especially for hard aid or free climbing, and its silky smooth trigger action allows for quick placements and removal. The longer body affords additional reach when top-stepping or stretching for that hard-to-get placement, and the Range Finder on the cam lobes you get a quick look assessment to whether or not the piece will be effective in its placement.
Each cam is hand-built in Bend, Oregon and is thoroughly inspected and every unit is tested to 5 kN. Master Cams are CE and UIAA certified.
