Arborist-specific: DMM Pinto Pulleys have a hot forged frame 7075 T6 aluminium for exceptional strength to weight ratio. The Pinto Rig (purple) (large) rigging pulley carries 6000-2RS series ball bearings. As compared with the Pinto Red (small) Pinto pulley carries an oilite bushing. Spliced or stitched terminations can be made directly to the rounded cross section of the attachment holes or the curved becket. All sorts of wonderful configurations become possible. Fair-lead flares and rounded cheek plate edges that help maintain high working efficiency. Size of attachment holes reduce probability of locking carabiner rotation. Compatible with DMM Ultra O and Boa carabiners. Tamper proof construction. Direct connection to textile components at the rounded cross section of anchor holes and curved becket. Textile connections can reduce system costs, increase lift height in mechanical advantage systems, and increase tolerance to torsion.
