Notch Large Stainless Steel Portawrap – Rope Friction Lowering Device

Designed for professional arborists and rigging crews who require controlled, predictable rope friction when lowering heavy timber during dismantling operations. The Notch Portawrap is a lightweight, compact rope friction device created to lower heavy loads in a controlled and efficient manner. Originally designed by arborists Scott Prophett and Norm Hall in the early 1990s, the Portawrap has become a proven and highly dependable solution for safe and efficient rigging work.

Before the Portawrap, ground workers commonly wrapped ropes around nearby trees to control heavy wood, often damaging the “wrap tree” through surface friction. The Portawrap eliminates this problem by providing consistent, predictable friction that does not change with tree surface conditions. This allows the groundsman to focus entirely on load dynamics rather than friction inconsistency.

Key Features & Benefits

• Controlled rope friction: Provides predictable, repeatable friction for safe and efficient lowering of limbs and timber.
• Quick setup between loads: Easily wrapped and unwrapped for rapid repositioning during multiple lowering operations.
• Rust-proof stainless steel construction: Offers significant corrosion resistance for use in harsh environments including coastal conditions.
• Seamless main tube: Maximises strength-to-weight ratio and provides uniform mechanical properties for demanding rigging applications.
• Chamfered edges and posts: Eliminates sharp edges to protect ropes and improve handling safety.
• Tree-protecting cap (Scott Prophett feature): Prevents gouging and damage to the tree during use.
• Strength & rope specs labelled: Key specifications are clearly marked directly on the Portawrap unit.

Why Choose the Notch Large Stainless Steel Portawrap?

The Portawrap transformed modern arborist rigging by eliminating the need to wrap ropes directly around trees for friction control. With its predictable friction performance, seamless stainless steel tube and corrosion-resistant construction, it delivers consistent handling during complex lowering operations.

The inclusion of the Scott Prophett tree-protecting cap further enhances its professional design by preventing damage to the tree while maintaining full friction control. Built to withstand heat, salt and humidity, this Portawrap is equally at home in inland forestry operations and demanding coastal environments.
