The RollnAnchor Pulley is machined from a solid block of aircraft grade aluminum and was designed in partnership with 3 Strand Design, owned and led by a field arborist.  Its beefy tensile strength and flat surface make it ideal for use as a cinched canopy anchor.  The pulley makes retrieving redirected canopy-anchored lines easier and less gear-intensive than with other options.  When incorporated with a friction saver, the RollnAnchor pulley reduces friction, making for a smoother climb.  

The high tensile strength makes rescuable systems possible, as well.  While the axle's MBS is 8,000 lbs., any rope configuration that incorporates the plate benefits from the 10+k rating.  The openings allow for a bight or two lines to pass through, which means an access line, whether separate or isolated by knots, can be incorporated into anchor systems using the RollnAnchor. 

Only properly trained professionals should build systems intended for possible rescue, to ensure all parts of the system are properly rated and installed.
