The patent-pending ARS Magnapulley is a Double Sheave Pulley that splits apart into two Single Sheave Pulleys.
With two sets in your kit, you’ve got access to 2 Doubles, 1 Double and 2 Singles, or 4 Singles allowing you to construct 1×1, 2×1, 3×1 Z, 3×1 B&T, 4×1 B&T, 5×1 B&T, 6×1 Tripod Pass Through, and 9×1 Mechanical Advantage systems.
Although some kits are available with Magnapulley included, they are a fairly inexpensive addition to your existing gear.
They are made from 7075 Aluminum and the two individual pulleys are held together by four Neodymium Magnets embedded in the back plate.
Strength Ratings:
-Double Pulley 3 Sigma Strength Rating: 40kN
-Single Pulley 3 Sigma Strength Rating: 28kN
-Double Pulley Becket 3 Sigma Strength Rating: 50kN
-Single Pulley Becket 3 Sigma Strength Rating: 26kN
Here’s a pretty complex application, a 5:1 mechanical advantage system using Magnapulley.
An important note: Magnapulley is tested to and exceeds the NFPA Standard 1983 (2017 ed) for Technical use. But the are *NOT NFPA CERTIFIED*. This is because of their type and not because they can’t pass.

these are some badass pulleys
This is a fellow Big City firefighter brother. He makes rock solid life saving equipment.
The Tibloc is clipped incorrectly.
Well, before you comment you should know that the Tribloc sits just fine.
Which Tibloc are you referring to?
2 most important parameters are not mentioned – so I guess this is tactical crap: Weight and Bearing Efficiency. I dont see any reason to replace HAS, ISC or DMM Products in the Tactical High Angle World.
We did not write this article, so every detail is not included. Weight is 8oz and Efficiency is 90% or greater depending on Rope diameter and material type. All the companies you mention make great gear, some of which we incorporate in our kit. The Magnapulleys are the only pulleys on the market, however, that offer the unique functionality of splitting apart a double sheave pulley or cleanly combining two single sheave pulleys.
