PORTAWRAP

Portable rope friction device used for controlling the descent of limbs, branches and wood sections in 

tree care operations.

WARNING!

This device is intended for use by trained and 

skilled rope technicians only. Read instructions 

thoroughly and practice use away from people and 

valuable property before engaging heavy loads (in 

excess of 100 pounds). Use or misuse of this prod-

uct can result in injury or death. Use with caution. 

Not designed for human support or transport.

WARNING!

Thoroughly inspect target and work site for potential 

hazards and adjust accordingly. When rigging trees, 

aside from inspecting tree’s trunk and anticipated 

anchor point(s), also inspect tree parts that might 

break free in the process of removing connected 

sections! And also, as a general statement, tree fail-

ures can occur underground, so carefully inspect the 

surrounding ground for signs of root related decay 

or other weaknesses.

DO NOT CONNECT Portawrap to sling with SNAP 

OR OTHER METAL CONNECTOR (always connect 

sling with girth hitch directly to sling loop)

DO NOT attempt to control rope within 2-feet of de-

vice (hands could get sucked into rope path)

DO NOT OPERATE without first bundling long hair 

or removing loose clothing or risk entanglement

MAKE SURE you have enough rope to land target-

ed load safetly onto landing zone

DON’T OVER ESTIMATE the strength of your an-

chor point(s) or ropes. Expect the unexpected and 

always have an escape plan from a hazard zone.
