2. removing TRI CAMS from your rack with one hand and cocking the sling into the cam channel until the necessary motions come naturally This is a skill that must be acquired before you get out on a difficult lead Fig F DIRECTIONAL CONSIDERATIONS When used as a normal nut ina crack with a constriction TRI CAMS are usually more directionally stable than most conventional nuts because of the ability to key the cam rails over an irregularity However when used in their normal camming mode in some placements they must be carefully runnered and or used in opposition to each other You must consider how the forces of a fall will be transferred by the rope not only to the top nut but also to Py MSH those below see Fig H It is possible to wedge a TRI CAM more securely in place by giving it a tap or two downward near the Stingers with a nut tool or hammer but this is using a TRI CAM as a piton When used in the tight fitting attitude TRI CAMS are very secure and will resist considerable outward and even upward force once you ve set them with a good jerk on the sling Figure H Vertical Placement Constant Tension Bungy eed CONSTANT TENSION LOOPs It s a good idea to carry three or four loops tied from 2 lengths of light weight elastic EEERE G Shallow Horizontal Crack Placement Conch Tencion Das Bungy Loop h AN ae a Hae i bungy cord These loops can be used to e

TRI CAM C A M P TRI CAMS are the result of many year s evolution in cam nut design You ll find C A M P is TRI CAMS to be the most versatile artificial chock stones you ve ever used With a little practice TRI CAMS allow easy secure one hand placement in normal and exotic situations In addition to protecting you where conventional nuts will work TRI CAMS will protect you where absolutely nothing else can The TRI CAMS design create a stable tripod with the two parallel camming rails flat against one side of the crack and the fulcrum point contacting the Opposite side This tripod can be set solidly with a downward jerk on the sling TRI CAMS are easily removed even after a fall Parallel sided cracks shallowholes horizontal outward flares Bombay flares all are TRI CAM placements Eleven overlapping sizes fit cracks from 16 mm to 140 mm Sizes 0 5 through 4 TRI CAMS are forged and 5 6 and 7 are Stamped The bodies are hardened aircraft aluminium with stainless steel sling retaining pins Each TRI CAM comes equipped with a sewn sling Why TRI Cams Although spring loaded cams are convenient they have several drawbacks Mechanical complexity makes them susceptible to breakage They are expensive both to manufacture and to buy They have the unwanted tendency to walk deeper into cracks and in other ways too resist extraction Spring cams also cannot be used in many normal nut placement The TRI CAMS is the first sin

5. gle piece cam nuts that really work METHOD OF PLACEMENT NORMAL TRI CAMS work very well as a normal nut in constricted cracks Fig A The tri pod configuration actually allows a placement that in most cases is Figure A more secure than a conventional nut Use the cam channel to straddle a bump or rugosity ALWAYS MAKE CERTAIN THAT BOTH CAM RAILS ARE CONTACTING THE ROCK as well as the fulcrum point do that a true tri pod is achieved STANDARD In a vertical parallel sided or flared crack place the TRI CAM as in Fig B Cock the TRI CAM by running the sling down the cam channel Look for a rugosity of some sort on which to position the fulcrum point This is not absolutely necessary but often makes the placement more secure Give a good jerk on the sling to set the nut Figure B HORIZONTAL Fig C In horizontal or diagonal cracks you have a choice of Figure C positioning the TRI CAM fulcrum up or fulcrum down Neither way is best in all situations Sometimes if you re climbing directly above the placement fulcrum down will offer the greatest security At other times when traversing or angling away from the placement it s best to have the fulcrum up But there are no hard and fast rules for this TIGHT FIT CAMMING For parallel sided cracks there is an additional effective camming mode in which TRI CAMS may be used As in the Fig D ifthe TRI i KUUE E CAM fits tightly i
6. nto a crack in the attitude shown a small camming effect is created enough so that good protection is afforded OTHER PLACEMENTS TRI CAMS are the most secure form of protection available when used in icy cracks or cracks formed by ice and rock Just make certain to use the largest size of TRI CAM possible as under the weight of the sling and carabiner alone the fulcrum point will melt into the ice until the cam shoulders contact the ice Take this into consideration when arranging a belay and don t apply long term strain to a TRI CAM used between ice and rock TRI CAMS work very well in holes flares up under flakes and so on Always remember however to ascertain that both cam rails and the fulcrum point are in contact with the rock otherwise the TRI CAMS will be unstable LEADING Please do not learn to use TRI CAMS ona lead TRI CAMS require some getting used to An analogy may be drawn with climbers who grew up with pitons making the switch to nuts At first nuts seemed insecure but as familiarity grew their advantages became evident RACKING Sizes 0 5 1 1 5 2 2 5 3 3 5 and 4 TRI CAMS may be carried singly or in multiples on carabiners But the larger sizes are best carried by clipping the sling and the channel pin that is located near the cam shoulders through the carabiner This keeps the TRI CAM from Swinging down around the knees see figure E ONE HANDED PLACEMENT Practice
