Black Poly

100% monofilament, extruded from virgin resins with a firmer lay than standard polypropylene.

Floating

SuperPro®

Using S.I.M.A. extrusion process, this rope is a blend of polypropylene and high modulus polyethylene resins to produce a fiber with superior tension and bend fatigue performance. SuperPro® is 35% stronger and ten times the abrasion resistance of conventional monofilament polypropylene products, with low-elongation characteristics equivalent to polyester. SuperPro® "co-polymer" rope offers the best performance/price value.

Floating

Easy Haul

A coarser texture than Super Haul. Made with alternating black polypropylene and white polyester yarns within each of the three strands. This construction results in a slightly firmer lay than Super Haul.

Sinking

Orco Offshore Potwarp

A larger diameter, firm lay, sinking potwarp constructed of all polyester veneered co-polymer yarns - core and cover. This rope combines very high strength with low stretch for smooth hauling. Two blue tracers.

Sinking

Extra-Lene Offshore Potwarp

Same construction as Orco Offshore but with economical polypropylene instead of co-polymer. One green tracer.

Sinking

Super Haul

A standard in the commercial fishing industry. A plied yarn construction of 100% polyester strand cover over polypropylene yarn strand core twisted in a firm lay. Product features include low noise in the hauler, excellent on-deck handling, and superior abrasion resistance.

Sinking

Easy Haul Plus

A long-lasting sinking potwarp. Manufactured with a firm lay and the distinctive striping of alternating blue "SuperPro" co-polymer and white polyester yarns. Greater strength and abrasion resistance relative to Easy Haul.

Sinking

Orco Haul

Highest tenacity potwarp. Every yarn consists of a blue "SuperPro" co-polymer core covered with a generous polyester veneer.

Sinking

Hoverline

A thoroughly tested and engineered, neutrally buoyant rope. This rope will not lie on the bottom and become fouled with grit or float high in the water column and entangle whales.

Neutrally buoyant

Offshore Polypropylene

A specially constructed yellow (other colors available) monofilament polypropylene in a firm lay.

Floating

TENSILE STRENGTHS: are determined from tests on new, unused rope in accordance with standard test methods of the Cordage Institute.

CAUTION: USE OF WORKING LOADS

Because of the wide range of rope use, rope condition, exposure to the several factors affecting rope behavior, and the degree of risk to life and property involved, it is impossible to make blanket recommendations as to working loads. However, to provide guidelines, working loads are tabulated for rope in good condition with appropriate splices, in non-critical applications and under normal service conditions.

The Cordage Institute Formula for working load is:

Working Load = Minimum Breaking Strength/Safety Factor

A higher working load may be selected only with expert knowledge of conditions and professional estimate of risk. Also, if the rope has not been subject to dynamic loading or other excessive use, has been inspected and found to be in good condition, is to be used in the recommended manner; if the application does not involve elevated temperatures, extended periods under load, or obvious dynamic loading (see explanation below) such as sudden drops, snubs or pickups. For all such applications and for applications involving more severe exposure conditions, or for recommendations on special applications, call Jay at 612-282-4035.

**Many uses of rope involve serious risk of injury to personnel or damage to valuable property. This danger is often obvious, as when a heavy load is supported above one or more workmen. An equally dangerous situation occurs if personnel are in line with a rope under tension. Should the rope fail, it may recoil with considerable force. Persons should be warned against the serious danger of standing in line with any rope under tension. IN ALL CASES WHERE SUCH RISKS ARE PRESENT, THERE IS ANY QUESTION ABOUT THE LOADS INVOLVED OR QUESTIONS ABOUT THE CONDITIONS OF USE, THE WORKING LOAD SHOULD BE SUBSTANTIALLY REDUCED AND THE ROPE PROPERLY INSPECTED.

DYNAMIC LOADING VOIDS NORMAL WORKING LOADS

Normal working loads are not applicable when the rope is subject to significant dynamic loading. Whenever a load is picked up, stopped, moved or swung there is an increased force due to dynamic loading. The more rapidly or suddenly such actions occur, the greater the increase will be. In extreme cases, the force put on the rope may be two, three or even more times the normal involved. Examples could be picking up a tow on a slack line or using a rope to stop a falling object. Therefore, in all such applications such as towing lines, lifelines, safety lines, climbing ropes, etc. working loads as given DO NOT APPLY.

Users should be aware that dynamic effects are greater on a low elongation rope such as polyester than on a high elongation rope such as nylon, and greater on a shorter rope than on a longer one. The working load ratios listed contain provision for very modest dynamic loads. This means, however, that when this working load has been used to select a rope, the load must be handled slowly and smoothly to minimize dynamic effects and avoid exceeding the provision for them.

EFFECT OF TEMPERATURE ON TENSILE STRENGTH

The tensile strength charts apply to ropes tested at normal room temperature (70°F). Ropes have lower tensile strengths at higher temperatures. 30°F (or more) lower at the boiling point of water (212°F) and continuing on down to zero strengths for nylon and polyester at 490°F and 300°F for polypropylene.

Also, continued exposure at elevated temperatures causes permanent damage. TENSILE STRENGTHS shown are average based on new ropes tested under laboratory conditions, minimum can vary by 10%.
