Notch Medium Portawrap
The Notch Portawrap is a proven arborist lowering device designed to provide consistent, predictable friction when controlling heavy limbs, logs, and other tree sections. Originally developed by arborists Scott Prophett and Norm Hall, it gives ground crews greater control over rigging loads while helping protect nearby trees and property from damage.
Instead of wrapping a lowering line around a tree trunk—which can damage the bark and produce inconsistent friction—the Portawrap creates a compact, dedicated friction point. The lowering rope can be wrapped, adjusted, and removed quickly between loads, helping ground workers manage rigging operations efficiently while keeping the work area organized.
Made from rust-proof stainless steel, this medium Portawrap offers excellent resistance to heat, salt, moisture, and corrosion. Its seamless main tube delivers a strong, uniform construction, while chamfered edges help protect ropes from sharp surfaces. An integrated tree-protection cap helps prevent the gouging and trunk damage that may occur with other lowering devices.

Safety Notice: The Portawrap is a rigging and lowering device—not personal protective equipment or a life-support device. It must be secured using a correctly configured and appropriately rated attachment sling. Follow the manufacturer’s instructions, observe all marked strength and rope specifications, and inspect the device, rope, sling, and complete rigging system before every use.
