Description
Husky Arborist Bull Rope, made by AllGear, is a composite rigging line: a double braid polyester jacket over a nylon core, finished with a Husky urethane coating. The jacket and coating give it extra abrasion resistance, and the nylon core lets it take some shock-loading. It's made for pulling trees and rigging limbs, and it can be used in a knotless rigging system, where several branches are cut and lowered at once. Among our bull ropes with a polyester jacket and a nylon core, Husky is the strongest and the Best step, above TreeBLITZ (Great) and V-HEX (Better), which have no urethane coating.
- Sizes 1/4 in to 1 in
- Color-coded: each diameter comes in one color only
- Double braid, so it can be spliced
- Stretches 7% at 30% of its tensile strength
- Use a 5 to 1 safety factor: divide the breaking strength by 5 for the working load limit
Questions
About the rope
What is it made of?
A double braid polyester jacket over a nylon core. It has a Husky urethane coating for abrasion resistance. Sizes run from 1/4 in to 1 in.
How do I choose a color?
Each diameter is its own color so you can tell sizes apart quickly. That means each diameter comes in one color only.
Does it come in other colors?
No. The colors set by diameter are the only ones available.
Can I splice it?
Yes. It is a double braid rope and can be spliced.
What are its specs?
Elongation is 7% at 30% of tensile strength. Specific gravity is 1.38.
Choosing a bull rope
How does it compare with TreeBLITZ and V-HEX?
Those are also polyester jacket over nylon core ropes, but they have no urethane coating and are not as strong as Husky. Our ladder is TreeBLITZ (Great), V-HEX (Better) and Husky (Best).
Strength and safety
How do I work out the working load limit?
We recommend a 5:1 safety factor. Divide the breaking strength for your diameter by 5. Do not exceed that working load limit.
Breaking strength is the force that breaks new rope under perfect conditions. The working load limit is what the rope can handle in real use without damage. Going over it can weaken the rope in ways you may not see right away.
Where a failure could cause certain injury or death, use a safety factor of 12. The less ideal the use, the higher the factor should be.
Do knots weaken the rope? What about splices?
Yes. A bowline or clove hitch can reduce breaking strength by about 40%. Some knots reduce it by up to 60%. A figure-eight is the best choice, at about 25%. Raise the safety factor to allow for this.
A well-made eye splice keeps 85 to 95 percent of the rope's strength, especially with a thimble. If you have doubts, speak with a seasoned professional.

How does a safety factor work out in real numbers?
The safe working load limit (SWLL, or WLL) is typically the breaking strength divided by 5. The more dangerous the use, or the less ideal the use of the rope, the higher the safety factor should be.
Working out your safety factor and SWLL takes some experience, the ability to recognize real-world physics, and knowing the history of your rope.
Here is one example, a 1 inch piece of HMPE rope with a breaking strength of 110,000 lb:
- Low-danger operation, safety factor 5: up to 22,000 lb (110,000 divided by 5)
- A failure would be catastrophic, such as causing certain injury or death, safety factor 12: 9,166 lb (110,000 divided by 12)
- That same piece of HMPE used for a low-risk operation, but with a figure-eight knot on a bight (non-ideal use of the rope), should have a safety factor of more like 7, putting SWLL at 15,700 lb
What happens if I go over the working load limit?
If you stay at or under the SWLL, you have a much lower chance of a break, which means a much lower chance of an accident.
Exceeding it may weaken or damage the rope, often in ways that are not immediately obvious. The more often you exceed it, the easier it will be to break the rope. Respecting the working load limit is one of the most reliable ways to avoid accidents and get the most out of your gear.
Why do knots weaken rope, and when is a splice better?
Many rope users don't realize that knots reduce rope strength significantly. Knots create sharp bends and friction points that concentrate stress on the rope fibers. Some knots slip under load, and others can jam so tightly that they damage the rope permanently. Make sure if you are using any knots that you factor that in to your SWLL, increasing the safety factor by a representative amount.
In heavy rigging, lifting and towing, splices are much safer because they preserve most of the rope's original strength. A well-made eye splice maintains 85 to 95 percent of the rope's strength, especially when paired with a thimble to maintain proper bend radius.
Rope safety means knowing which knots to use, when a splice is the better option, and how different tying methods affect load capacity. If you have doubts about your ability to calculate the proper SWLL, speak with a seasoned professional, and err on the side of caution.
