GENERAL PURPOSE

Synthetic rope

encompass versatile, cost-effective fiber line assemblies manufactured from nylon, polyester, polypropylene, and composite blends in 3-strand, 8-strand, and braided constructions, engineered for utility mooring, barge tie-downs, towing, deck rigging, and general industrial load-securing operations.

Available in Nylon (high shock absorption), Polyester (low stretch & UV resistance), Polypropylene (lightweight & buoyant), and Poly-Dacron blends for specialized duty cycles.

Offered in classic 3-Strand Laid/Twisted, 8-Strand Plaited, and Double Braid configurations to match manual handling, capstans, winches, and deck fittings.

Nylon variants provide superior energy absorption to cushion sudden dynamic snap-loads during towing and mooring in rough seas.

Manufactured and proof-tested in full accordance with Cordage Institute (CI) standards for breaking strength, linear density, and elongation limits.

3-Strand Twisted Synthetic Ropes
- Diameter Range: 1/4 in – 2 in+ (6 mm – 50 mm+)
- Fiber Material Options:
  - Nylon: High elasticity and strength; absorbs high shock loads during dynamic mooring and towing
  - Polypropylene: Lightweight, floating monofilament line ideal for water barrier lines and marine utility
  - Poly-Dacron: Polyester jacket over polypropylene core strands combining high abrasion resistance with light weight
- Primary Feature: Classic laid design that is easy to tuck-splice in the field and provides excellent general-duty versatility
- Compliance: Cordage Institute CI-1303 / CI-1308
Double Braid Synthetic Ropes
- Diameter Range: 3/8 in – 2 in+ (10 mm – 50 mm+)
- Fiber Material Options: Nylon-on-Nylon (high stretch/strength), Polyester-on-Polyester (low stretch/high UV resistance)
- Construction: Load-bearing braided inner core encased in a high-density braided outer sleeve
- Primary Feature: Completely torque-neutral construction that will not kink or hockle under load; offers superior strength-to-diameter ratios and smooth running through blocks and capstans
- Compliance: Cordage Institute CI-1310 / CI-1311
8-Strand Plaited Utility Ropes
- Diameter Range: 5/8 in – 3 in+ (16 mm – 76 mm+)
- Fiber Material Options: Polypropylene, Poly-Dacron Composite, Nylon
- Construction: 8-strand torque-balanced square plaited weave
- Primary Feature: Designed to lie flat on winch drums and bitts without hockling, twisting, or spinning under heavy strain; ideal for commercial barge tie-downs and ship mooring lines
- Compliance: Cordage Institute CI-1305
