The Redesigned Conterra Edgebot is an ultra compact, high efficiency roller that is packed with features. It is uniquely shaped to work on railings, logs, rocks, guard rails, parapits, or anywhere else that friction needs to be addressed. It can be hobbled down with rope or webbing, hung by biners, or even slid along tracks made by 8mm utility cord. The Edgebot features stainless steel axles, bronze bearings, aircraft aluminium tires and powder coated side plates. Triangular openings allow biners to redirect off angle ropes. The underside is curved to work on varied surfaces, and sports 'crampons' which help with guard rails and parapits. Built in USA, right in Conterra's ISO 9001:2008 CERTIFIED machine shop.
