Rock Exotica Enforcer with Case

The Rock Exotica Enforcer is a portable load cell that clips inline in a rope system and records the forces it sees. Arborists use it to measure rigging loads, compare techniques, and teach crews what a drop actually puts on the gear.

Why measure forces

Most rigging decisions are made by feel: how big a piece, how much run, how hard to let it run. A load cell replaces guesswork with a number. Put the Enforcer inline between the rigging point and the block or lowering device, take a cut, and you see the peak force the system saw. Do the same piece with more friction or a shorter drop and the difference is obvious.

That makes it a strong training tool. New climbers learn quickly why a small piece dropped a few feet loads a rigging point more than they expected. See more specialty gear in our other gear section.

Using it safely

A load cell is an instrument, not a rigging connector to leave in the system. Use it within its rated range and the maker's instructions, check the batteries and calibration as directed, and keep it in the case between jobs.

Testing rigging loads means setting up controlled drops, so plan them carefully. Keep everyone out of the drop zone, use rated hardware throughout, and follow ANSI Z133 practice. Treat the numbers as a guide to better rigging, not permission to push gear closer to its limits.

Record what you test. A short log of piece size, drop, friction setup, and peak load gives your crew a reference that is far more useful than memory.
