Key Features
SAMSON 1/2" TRUE-BLUE 150' HANK
Pros & Cons
👍 Pros
- Consistent knot-holding from the 12-strand braid gives reliable friction hitch performance climb after climb
- Polyester construction resists rot, mildew, and UV degradation, holding up across seasons of outdoor use
- 7,300 lb tensile strength provides a strong safety margin for professional climbing loads
- Low elongation at 3.46% means minimal stretch under working loads, translating to predictable, controlled ascents
- Smooth braided surface runs cleanly through pulleys, cambium savers, and mechanical devices without snagging
👎 Cons
- At 150 feet, the hank length may be too short for tall timber work where 200-foot lines are standard
- The 1/2-inch diameter creates more bulk on a harness saddle compared to thinner 11mm climbing lines
- Polyester has less shock-absorption capacity than nylon, which matters in dynamic fall scenarios
- The rope can feel slick when brand new until the surface fibers break in after several sessions
Frequently Asked Questions
Is this rope suitable for tree climbing and arborist work?
Yes. The Samson True Blue is an industry-standard arborist climbing line. Its 12-strand braided construction provides excellent knot-holding and flexibility for friction hitches and climbing systems used in professional tree care.
What is the tensile strength and is it rated for life safety?
The True Blue has a tensile strength of 7,300 lbs (32.5 kN). It is widely used by professional arborists as a climbing line, but always verify that your specific application meets current ANSI Z133 standards and your employer's safety requirements.
Does this rope hold up in wet conditions?
The polyester construction resists rot, mildew, and moisture absorption, so the rope maintains its strength and handling characteristics in rain and humid environments. It will not stiffen or degrade the way nylon ropes can when repeatedly soaked.
How does the 12-strand braid affect knot tying compared to a 3-strand rope?
The 12-strand braid is more flexible and rounder in cross-section than a 3-strand, which makes it easier to tie, dress, and release knots. It also runs more smoothly through pulleys and friction devices, which is a significant advantage during extended climbing sessions.
Can I splice this rope?
Yes. The 12-strand construction is spliceable, which allows you to create professional eye splices for attachment points. Splicing maintains more of the rope's rated strength compared to knotted terminations.
