TWIST chest ascender rope access device with X-Cam design which can be used with combination harness or with separate sit & chest harness.

When tested on new Tectra 11 mm low stretch rope, our X-Cam ascenders were found to be 25% stronger than their most popular sharp toothed competitor, with average breaking loads up to 675 kg for X-Cams versus 535 kg for the established design.

X-Cam has a more advanced tooth design than traditional cams and is more suitable for industrial applications as it does not pluck the rope, so reducing rate of rope wear.
