The Triberion 15-ounce arborist throw line kit gives tree-care users a middle-weight bag and a long, slick line for controlled limb placement. Fifteen ounces offers a compromise between the easy acceleration of a lighter bag and the branch-dropping pull of a heavier option. The kit is intended for positioning a separate working line; the included throw line is not a climbing rope.

How to decide if it fits your project
A 15-ounce bag is a practical middle choice if 12 ounces feels too light to return through foliage but 16 ounces is unnecessarily tiring. Canopy density, branch bark, line diameter, throw method, and user experience all affect performance. Select a different weight when a particular tree or technique demands it, and keep spare line available for retrieval problems.
Use and care
Flake the line into a clean throw cube or container rather than winding it tightly around an arm. Dry wet line and bag before storage. Inspect stitching, attachment points, line abrasion, knots, and the bag covering before every use. Remove grit and debris that can increase friction or damage bark, and retire equipment with torn seams or uncertain integrity.
Important safety note
Establish an exclusion zone and inspect for people, vehicles, glass, animals, electrical conductors, dead limbs, and other overhead hazards. Wear suitable eye and head protection. Never use the throw line itself for climbing, life support, rigging, or lifting.

Frequently asked questions
Why choose a 15-ounce throw bag?
It sits between lighter 12- and 14-ounce options and a heavier 16-ounce bag, offering a versatile balance of throw effort and return weight.
Is the 166-foot line a climbing rope?
No. It is a lightweight placement line used to install separately rated climbing or rigging equipment.
How should I store the line?
Flake it loosely into a clean container, remove tangles, and let all components dry before storage.
Can it be used near power lines?
No. Keep throw-line work well away from electrical conductors and follow applicable professional clearance requirements.
