CMC Ultra-Pro Edge ProtectorsFEATURES A CMC Rescue Exclusive The most sought after edge protection available features super slick, high performance material that not only protects your rope from sharp or rough edges, but also greatly reduces friction. The Ultra Pro is lighter and easier to transport than edge rollers or similar devices and its lower profile avoids tipping often encountered with taller devices. It conforms to the edge, and prevents sharp bends in the rope.
