Custom and Specialty Ropes

HOW TO BUY  

SP-12

SP-12 is a 12-strand blended rope comprised of Honeywell Spectra® fiber and polyester. This rope is designed to take advantage of the high strength and low elongation properties of Spectra® fibers while providing a slightly lower price point than 100% Spectra® ropes.

The primary market opportunity is for long length conducer pulling machinery. This rope can also be used in any application where 100% Spectra® does not fit the need and 100% polyester is limited in selection as well. The rope is available in any of our Maxijacket HP colors which will be supplied as a standard coating. This product is identified by the addition of blue polyester fiber in the strand bundle of yarn.

* 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.

Dielectric Strength: The maximum allowable leakage for clean, dry SP-12 is 100 micro-amperes when tested at 100kV per Yale Method 712-1701 Rev 1 “Routine Production Test.”Absorbed and entrained moisture or impurities will increase rope’s conductivity dramatically.
