Notch Portawrap IV Medium Stainless Steel – Rope Friction Lowering Device

Designed for professional arborists and rigging crews who require predictable, controlled lowering of heavy wood during dismantling and sectional felling operations. The Notch Portawrap is a lightweight and compact rope friction device designed for lowering heavy wood in a controlled manner. Originally designed by arborists Scott Prophett and Norm Hall in the early 1990s and first introduced and manufactured exclusively by Notch, the Portawrap has proven itself as a highly dependable and effective tool for sparing properties from the damage caused by free-falling tree parts.

Historically, groundsmen controlled heavy wood by wrapping the running end of a rope around a nearby tree, often damaging the bark through surface friction. The Portawrap replaces this method by offering predictable, unchanging rope friction in a compact, easily maintained working area. It allows quick wrapping and unwrapping between loads, turning complex lowering operations into a smooth, controlled process so the groundsman can focus strictly on the dynamics of the activity above.

Key Features & Benefits
