Pulling Tape & Rope Overview:

Due to the wide range of pulling rope available, as well as the myriad of variables involved, there is no one size fits all pulling rope. The pulling rope purpose, condition, and environmental exposure all factor into the decision to purchase. We provide pulling rope of varying tensile strengths, diameters, and materials to suit your application. These tensile strengths are based upon tests of new and unused rope with appropriate splices. Not only is the decision on what pulling rope to purchase important, but also how you care for and inspect the rope prior to usage.

Proper Care and Use


Dynamic Loading Voids Normal Work Loads

Dynamic loading occurs when pulling rope is subjected to sudden or extreme stress. Figures given as working loads are void if rope has been subjected to dynamic loading, high temperatures, long loading periods, extreme stress, improper storage, or incorrect usage.

Effect of Temperature on Tensile Strength

Tensile strength charts apply to ropes tested at normal room temperature (70°F) Pulling rope has lower tensile strength at higher temperatures, and continued exposure to elevated temperatures causes permanent damage. That's why it is necessary to store pulling rope in a dry, secure location out of sunlight or heat.

Avoid Abrasion

Pulling rope should be protected against sharp edges and abrasive surfaces. When worn areas are visible, tensile strength is compromised. To sustain the life and safety of using pulling rope, protect the rope surface with chafing gear around the rope.

Avoid Chemicals

Acids and alkalis are damaging to ropes and fibers. Caution should be used when ropes are used around building cleaning acids, caustic soda, and paints. The pulling rope should be properly inspected prior to usage.

Rope Inspection

Inspection of pulling rope should be a continuous process taking place before, during, and after each use. When fiber shows wear in any area, the pulling rope should be re-spliced, downgraded, or replaced.

Knots and Splicing

Splicing should be used instead of knots. Knots can decrease a rope's tensile strength by up to 50%.

Rope Storage

Pulling rope should always be stored in a clean and dry location, out of direct sunlight or exposure to extreme heat. Natural fiber ropes will deteriorate and rot over time if not stored in a dry location. Improper storage of pulling rope reduces tensile strength dramatically.

Sunlight Degradation

Pulling rope composed of polypropylene or polyethylene are subject to ultraviolet degradation. If there are any signs of discoloration or broken filaments, pulling rope should be replaced, as the tensile strength may be compromised.

Dielectric Properties

The dielectric properties of pulling rope must be tested under actual working conditions in order to get accurate results. The dielectric properties are upheld only for clean, unused pulling rope. Dirt, grease, moisture, and exposure to contaminants increase conductivity greatly. Nylon and natural fiber pulling rope should not be utilized around energized lines.


Pulling Rope Types

Double Braided Polyester Composite Pull Rope– This type of pulling rope is recommended for heavy duty cable installation applications where multiple cables are being installed. It exhibits low stretch characteristics with high tensile strength. This pulling rope is available in many diameters to suit the application, and comes in spools of 300, 600, and 1,200 feet. Our largest diameter pulling rope has a minimum break strength of 42,000 pounds.

Woven Polyester Pull Tape - Woven polyester pull tape can be utilized for both measuring and installing cable during a run. It generally features sequential footage markings for distance measurement, so you can measure and pull cable with one convenient product. Some of Primus Cable's woven polyester pull tape has silicone lubricant to greatly minimize burn through in PVC and HDPE ducts. It also has a low coefficient of friction which reduces burn through.

Twisted 3 Strand Rope – Three stranded polypropylene rope is made from premium grade ultraviolet stabilized polypropylene fiber. It is extremely versatile and also floats. This is suitable for light and medium duty applications. The mininum break strength ranges from 720 pounds per foot to up to 12,600 pounds per foot for the 1" diameter version.


Pulling Rope Products and Accessories

Professional Grade Heavy Duty Composite Double Braid Pulling Rope – Suitable for heavy duty pulling applications. It has factory spliced pulling eyes at each end, and is supplied in lengths of 300, 600, and 1,200 feet on a spool. The minimum break strength ranges from 5,000 to 42,000 pounds per foot.

Pull Tape 1800 Pound Tensile Strength Woven Polyester – This pull tape is available with a silicone lubricant comparable to that used in the manufacture of innerduct. It greatly reduces the chance of burn through. This woven polyester pull tape has printed sequential footage markings, so you can both measure and pull cable with one convenient product.

Poly Pull Line Spiral Wrapped Pulling Twine – This pulling twine is designed for pulling or blowing cable through conduit, suitable for light to medium duty applications. It comes packaged in a plastic pail of 6,500 foot length of pulling twine. The minimum tensile strength is 210 pounds.

Premium Grade U.V. Stabilized 3 Strand Rope – The three stranded polypropylene rope is made from premium grade ultraviolet stabilized polypropylene fiber. It is extremely versatile and also floats. This is suitable for light and medium duty applications. The mininum break strength ranges from 720 pounds per foot to up to 12,600 pounds per foot for the 1" diameter version.
