Tethys Pro Small Mobile Pulley

Lightweight and rather compact, the CAMP USA Tethys Pro Small Mobile Pulley easily carries on your harness and attaches to ropes up to 13mm. Like its less-intensive sibling, the Small Mobile Pulley, the Pro features an aluminum alloy body and stainless steel axle for durability on climbs and rescue scenarios. Unlike the Small Mobile Pulley, the Pro uses sealed ball bearings for high efficiency (92%) and intensive use at higher speeds. This pulley is prusik-minding, so it makes for ease in rigging a hauling system on routes or managing emergency rescue situations. Plus, it features a large connection point that accommodates two carabiners, as well as rotating side plates.

Perfect pulleys for a 2:1 haul sustem

I've put it through the wringer

I got a couple of these pulleys for a 2:1 haul system and they worked like a charm.

Worth the Weight

These pulleys have a super smooth action, and it's really noticeable when setting up a hauling system. I use these for glacier travel set ups primarily, and they work great. The getting a prussik minding pulley is definitely worth it. While there are plenty of similar options for pulleys out there, I think the Tethys Pro Small is an excellent value.
