Arbo Space Pluto Rigging Blocks are hand spliced with our, Arbo Space brand, 12 stand polyester rope. The coating on our rope aids in a higher resistance to abrasion, which adds longevity to our slings. This rigging block is 5/8” diameter and 6 feet in length. These six 8” pockets provide knot-free adjustments. This allows climbers to have all their needed adjustability, without the hassle of time consuming knoting. Durable, low-friction and heat-resistant are all the reasons we created our Lupex Rope.
