The Janus Pro by CAMP is a high-strength, multifunctional double pulley with large sheaves for high efficiency haul systems.

It uses the same design as the Janus with a main attachment hole that accommodates three carabiners, two secondary holes on the sides for positioning and a large lower becket hole, but features sealed ball bearings for higher efficiency and intensive use at higher speeds. Prusik knots can be installed on either side of the Janus Pro by CAMP (aramid cord suggested).
