Negative Block Rigging Kits

These kits utilize a loopie sling to install a block anywhere you need it in the tree. Running the supplied rigging rope through the block minimizes abrasion and wear and tear on your rope, and grants increased control of the load. Rate of descent is controlled through use of the Port-a-Wrap attached to the base of the tree with the Tenex sling. Everything you need in one kit, with built-in savings and a rope bag large enough for your rigging line, slings, and blocks.

Kits contain rigging rope and block, with loopie sling for attaching block in the tree, and Port-a-Wrap III with dead-eye sling for attaching at base of tree and managing the descent of the load.

Big Rig Kit

Big Rig Kit

Our biggest negative blocking/false crotch kit to date is based around the new XL Port-a-Wrap. The 3.5” bollard on the XL porty provides a good bend-radius for the 3/4” rigging line. The base sling is long enough to hang on stems up to 6' round, and the large ISC spring block will allow you to get large-diameter trunk sections down in an expedient fashion.

Kit contains: 200' Stable Braid 3/4" (SB3420), XL Nickle-plated Port-a-Wrap III (RIG142), 1" x 25' Double-braid Sling (SLI121), 3/4" Loopie Sling (SLI404), ISC Large 3/4" Aluminum Spring Block (PUL304), XL Rope Bag (BAG104)
