SMC combined 54 years of design and manufacturing knowledge with an uncompromising program of innovation, prototyping and user feedback to create our new Apex Swivel Pulley. The result is a pulley with unmatched security and deceptively simple ease of use. A patented, low-profile, triple-action lock prevents accidental openings, but the intuitive and ergonomic design can be opened with one hand. The robust lock is operated by three distinct actions: pivot the lock, depress the lock, and swing the side-plate. Simply closing the side-plate re-engages the lock and secures the rope. With symmetrical side-plates for optimized use with prusik-based progress capture systems this will minimize the possibility of mis-rigging. When unlocked, the side-plates swing away to streamline setup and offer maximum versatility when placing the pulley anywhere in your system. The cold-forged, custom designed swivel eye accommodates up to three carabiners and the rounded profile offers excellent soft goods compatibility when you want to eliminate the carabiner altogether. The APEX is best-in-class when you need a robust, versatile, and American-made pulley that is perfect for use in rescue, rope access, or arborism.
