No detail has been overlooked in our redesign of the ProSeries Pulleys. Built workhorse tough to deliver years of dependable service, these HD (Heavy Duty) Pulleys are loaded with enhanced features including:
Large high-efficiency anodized aluminum sheave
High-strength sealed bearings that minimize loss of mechanical advantage and will deliver optimum performance haul after haul
Side plates constructed of machined aircraft-grade aluminum, with smooth rounded edges to minimize rope wear
Wide attachment point that supports multiple rescue-size carabiners
PMP (Prusik-Minding Pulley) bottom shaped for maximum efficiency with Prusik hitches and also works well with mechanical rope-grabs
Note: Do not load a single side only of a double-sheave pulley.
