Available in a wide variety of designs and sizes, camming units offer stable protection for an array of climbing situations. Cams are spring loaded to allow for easy placement and removal, working on the principal that the head of the device will spread out as weight is applied to the unit and, thus, wedge itself into the crack to lock into place even more firmly. Along with camming units, rocks and nuts are the mainstay of any climber's rack. They fulfil a similar role to cams but are much lighter, allowing you to carry more of them for increased versatility. Their unique shapes and large size ranges provide multiple options for accurate and secure placing in cracks in the rockface. All of these products are individually colour-coded for rapid identification and placement.
