Maasdam Rope Puller Kit- with 200' Rope, Spliced Hook and Loopie Sling

Very high efficiency single pulley with one-way rotation and swivel.
Designed to be used in conjunction with a descender for maximum simplicity when setting up a heavy load deviation or haul systems for work at height or rescue.
Optimal hauling efficiency and lowering convenience: the faceted sheave only rotates in one direction, providing excellent efficiency when hauling and adding friction zones for the rope for additional braking when lowering heavy loads.
Easy handling: swivel allows pulley to be oriented under load and accepts up to three carabiners and allows the use of ropes and slings to facilitate maneuvers..
Sheave diameter: 40 mm maximum usage load: 3 x 2 = 6 kN.

Facilitates manipulations: - Keylock system prevents any accidental snagging of the carabiner when putting the pulley in place - gate opening on the pulley side facilitates installation of the rope when the pulley is fixed to the anchor - may be used with a CAPTIV positioning bar to favor loading of the carabiner along its major axis and to limit the risk of it flipping - sheave mounted on sealed ball bearings for excellent efficiency.
With TRIACT-LOCK locking system: may be used to minimize friction on the work rope while keeping set-ups simple. May also be used to install redirects..
H profile of carabiner: - ensures an improved strength-to-weight ratio - protects markings from abrasion.
Specifications Material(s): aluminum Min. rope diameter: 7 mm Max. rope diameter: 13 mm Sheave diameter: 18 mm Maximum working load: 2 x 2 = 4 kN Efficiency: 85 % Major axis strength: 20 kN Minor axis strength: 8 kN Open gate strength: 7 kN.
Warning: RollClip Triact- Lock can't be used with Ascender (doesn't fit through the holes).
