By machining the side plates, the thickness of the metal canbe varied to maximize the strength-to-weight ratio, a process that cannot be done with traditional bent metal sideplates. Sealed ball bearings provide high efficiency and aluminum side plates protect the rope. An extremely low-profilestainless steel axle assembly reduces snagging on rocks, roots, and uneven surfaces.Item # Type Color NFPA Rating 3σ MBS Sheave Tread Size Weight Price300301 Single Burgundy General Use 47 kN (10,566 lbf.) 1-1/2 x 1/2 in.

The rotating swivel aligns the rope with the direction ofthe pull. Its stainless steel sheave can be used with either rescue ropeor wire cable. By combining the swivel with the pulley, overall systemlength is minimized, increasing travel. The patented pivoting side plateallows the rope to be quickly inserted.• Stainless steel sheave allows use with wire cable• Prusik-minding side plate opens without havingto disconnect the pulley from the anchor• A double-detent button prevents accidental opening of side plate• Sealed ball bearings provide maximum efficiencyItem # Sheave Color NFPA Rating 3σ MBS Sheave Tread Size Weight Price300430 Stainless Steel Bronze/Slate General Use 39 kN (8,767 lbf.) 1-1/2 x 1/2 in.
