Light, Compact and Versatile: Our Pulley With Integrated Backstop

      The SPOC can be used as a classic rope clamp for rope ascents, as a simple pulley or as a pulley with a backstop, for example during crevasse rescue operations. It reaches an extremely high efficiency of 92%, thanks to the high quality ball bearing.

      The cam, with its integrated spring mechanism, locks automatically, and will work even with icy or muddy ropes due to its special design. A cable pull lets you easily open the backstop with one hand. The backstop can also be fixed in the open position in order to use the device as a simple pulley. The carabiner connection hole is generously dimensioned so that any type of screwgate carabiner can be positioned without problems, which makes the installation significantly simpler.

      The Spoc is suitable for ropes with a diameter between 7 and 11mm, as well as for the Rap Line II from EDELRID.

      The carabiner hole is generously dimensioned so that screw carabiners of all kinds can be turned in it without any problems, which makes installation much easier.

      The SPOC is suitable for ropes with a diameter of 7 - 11 mm as well as for the RAP LINE PROTECT PRO DRY 6.0 MM by EDELRID.
