The Portawrap is a lightweight and compact rope friction device designed for lowering heavy wood in a controlled manner.
Designed by arborists Scott Prophett and Norm Hall in the early 90s, the Portawrap has been proven a highly dependable and effective tool in sparing properties the damage inflicted by free-falling tree parts. In the past, a ground worker’s main option for rope-controlling heavy wood was to wrap the line’s running end around a nearby tree, often candy-striping the “wrap tree” from bark-scorching surface friction.
But now, in the time it once took to coil up a lowering line and walk it around a tree, the modern arborist can have a Portawrap prepped and ready for multiple lowering tasks. Quickly wrapped and unwrapped between loads, the Portawrap makes lowering wood out of a tree a smooth and simple process, all in a small, easily maintained space. And unlike the ever-changing tree trunk surface, the Portawrap presents predictable and unchanging friction to ropes, allowing the groundsman to concentrate strictly on the dynamics of the activity above.
The Portawrap has significant corrosion resistance. This rust-PROOF stainless-steel Portawrap will stand up to the worst heat, salt and humidity that a tree company can throw at it. Also included is a Scott Prophett special feature—a tree-protecting cap that bumpers the targeted tree from gouging whenever the Portawrap gets slapped with a nasty load.
