The AFB TS-1 allows a worker to control appropriate loads without an additional friction brake by simply holding the rope, whether on the ground or in the canopy. Made in the USA.

*Loads were measured with a static pull, NOT a drop test. Because force is increased by a fall, the manageable load does not necessarily reflect appropriate load weights.

Two wraps are recommended for best use. A wrap is defined as crossing the top of the device. Larger loads (up to 1,000 lbs) can be rigged with three wraps. With three wraps on the device it will be harder to pull rope back while unloaded, and this is recommended only for the occasional large loads or for controlling a rigging line placed at the butt of the load.

The Aerial Friction Brake is based on a rope and rescue tool created by Carroll C. Bassett called the BMS Belay Spool. The benefits of this improved, arborist-specific design include:

•Canopy controllable friction
•Snatch function allows easy attachment to the anchor sling and the ability to attach a rigging rope mid-line
•Extra wide side plates to prevent pinching of the running rope
•Square bollard decreases surface contact of unloaded rope, decreasing friction and allowing the unloaded rope to be pulled back (more difficult with three wraps)

Works well Review by Little A
Works well for me. I have used it on some big stuff. Dropped the tops out of 2 trees...probably more weight than it should have had but it held up fine. It has its limitations but if you have someone on the ground that is inexperienced, it is a good tool to have in the bag. I like it much better than old school wrapping the rope around the limb.
