Ascenders
We have a range of ascenders to suit rope access, caving and climbing. Our primary range of four Climbing Technology ascenders serves most purposes and features a unique patented pivoting action in the cam-release mechanism, which makes it easier to operate the cam, especially if a short section of down-climbing is required. We also offer CMI ascenders for those who prefer a more robust (though slightly heavier) ascender.

CMI Ultrascender – Small
The CMI Ultrascender is one of the strongest ascenders made. It is constructed of an extruded and machined body. The cams are made of 4140 chrome-moly steel which gives the cam the same corrosion resistance as stainless steel but increases both tensile and yield strength. The cams are harder than the best knife blades and are backed by CMI with a lifetime wear out guarantee. All springs and operating parts are constructed of stainless steel.
CT Quick Tree Universal Support
Universal fixing support for Quick Tree foot ascenders that can be installed onto any boot by using the webbing system with the adjustment buckle.
CT Quick Tree Spurs
