Domestic 1-1/4" 6x37 Bright Wire Rope - EIPS IWRC

Engineered in the USA using Extra Improved Plow Steel (EIPS), this 1-1/4" bright wire rope features a 6x36 construction and an Independent Wire Rope Core (IWRC) for maximum strength, flexibility, and fatigue resistance. Designed to perform in high-cycle lifting, winching, and suspension systems, it’s ideal for structural rigging where repeated bending is required.

High-Capacity Flexible Wire Rope for Rigging & Winch Systems

The 6x37 class enhances bendability and reduces fatigue failure, especially in applications that demand frequent movement. Though slightly less abrasion-resistant than 6x19 class rope, this rope excels in flexibility-focused environments. A petroleum-based lubricant protects both the internal and external strands from friction and light corrosion. This rope meets the dimensional and strength standards of RR-W-410 and ASTM A1023, ensuring it’s built for critical load-bearing jobs.

6x37 Wire Rope Configuration

Our wire rope is made using EIPS-grade cable. EIPS (Extra Improved Plow Steel) refers to the strength of the wire rope - its tensile strength is around 10% greater than an IPS grade, improving the break strength.

The class of this wire rope is 6x37. These numbers nominally refer to the construction of the wire rope - the number of outer strands around the core and an estimation of the number of wires within each of these outer strands. so for a 6x37 class, the number of outer strands is 6, and the number of wires making up each strand can range from 27-49. The construction of the rope you will be receiving is 6x36 - if you are looking for something different, please call.

Wire Rope by the Foot Ordering FAQ

Does this wire rope come as one length? Yes, the quantity you add to the cart will be provided as one unbroken length of rope. So if you add this to the cart with a quantity of 1000, you will receive one 1000-foot long rope.

Can I order multiple separate lengths? Yes. For example, if you need two 1500-foot lengths of rope, you would set the quantity to 1500 and then add that to the cart twice. For each separate instance you add this to the cart, you will get a separate length of rope.
