Sterling Atlas 3/4 in Rigging Rope

Sterling Atlas rigging rope in 3/4 in is a heavy lowering line for removal crews that regularly block down big wood. The diameter gives you more strength and more to hold onto on the port-a-wrap than a 1/2 or 5/8 line.

Where a 3/4 in line fits on the job

Most climbers rig small to mid-size pieces on 1/2 or 5/8 rope. A 3/4 in line like Sterling Atlas comes out when the wood gets heavy: big leaders on a removal, long spar sections blocked down with a large rigging block, or a crane-free takedown over a roof. The extra diameter adds strength and gives the groundie more rope to control the run.

The tradeoff is weight and bulk. A 3/4 in line fills a rope bag fast, needs a block and lowering device sized for it, and takes more effort to pull back up. Many crews keep one heavy line on the truck for the big jobs and run lighter rope day to day. See other options in rigging rope.

Setup, inspection, and care

Match the rope to your block sheave, port-a-wrap or capstan, and slings so that every part of the system is sized for the loads you plan to put on it. Confirm the rated strength with the seller and leave a healthy margin for shock loading when you let pieces run.

Look for glazing, pulled strands, cuts, and stiff or flat sections after each job, and retire rope that has taken a hard shock load or shows core damage. Keep it out of bar oil and fuel and store it dry. Rig only within the rated strength of every component in the system, inspect the rope before each job, and make sure the crew is trained in rigging practice under ANSI Z133 and the manufacturer's instructions.
