HOW TO BUY  

PoBOn

PoBOn is a double-braided rope consisting of a polyester sleeve covering an inner load-bearing core of 100% Zylon PBO polyester, a rigid isotropic crystal polymer. PoBOn has outstanding tensile strength, high modulus, flame resistance, and thermal stability.

It has little elastic elongation and is extremely strong. PoBOn exhibits no measurable creep and has excellent high-temperature resistance.

Construction: Core: 100% Zylon PBO urethaned for abrasion resistance. Sleeve: Braid of smooth filament polyester.

* Knots and abrupt bends significantly reduce the strength of all ropes and lower the maximum working load.
** Working load is based on static or moderately dynamic lifting/pulling operations. Instantaneous changes in load, up or down, in excess of 10% of the rope’s rated working load constitute hazardous shock load and would void the normal working-load recommendation. Consult Yale Cordage for guidelines for working loads and the safe use of rope.
