DCD stocks a complete range of Wire Mesh Grips.  In quality, size range, working load capacity and dimensional specification, they are the direct equivalent of the largest North American manufacturer.

While the types and sizes listed on the following tables are the most common to the Directional Drilling market, DCD is able to supply other types of grips including Strain Relief, Tension Relief and many other lighter weight pulling grips.  For additional details of different styles and sizes available follow this link .

Always read breaking strength and specifications when available.

Key Benefits

  • Familiar product
  • Different types according to application
  • Easy to order

The following selection chart is designed to make a product selection as simple as possible:

  1. Look up the Duct Size being pulled, either Imperial or Metric,

  2. Decide which of the Standard, Heavy Duty or Rotary Head type is best suited to the application,

  3. Read the Part Number of the required grip.

Technical Data:

Where Approximate Breaking Strength values are quoted, they represent the value at which each product has been tested to breaking. Safety factors must be determined by each different application. DCD recommends a minimum safety factor of 3 for underground pulls and 5 for overhead pulls. The Approximate Breaking Strength value will decrease with usage of the product due to metal fatigue.

Where Maximum Recommended Load values are stated, they represent the suggested maximum load that should be applied to the PE or PVC duct being pulled. Loading beyond those limits will exceed the Yield strength of the heaviest wall ducting and will probably result in damage to the ducting. For ducting with thinner or lighter wall sections, consult the manufacturer’s stated Yield values for each specific size and do not exceed those values during pullback.

The use of a Rotating Head does not negate the need for a swivel. The Rotating Head will rotate under no-load conditions providing it is clean and free of friction or other restraint. In a Directional Drilling application a proper swivel must be used at all times.

It is recommended that any use of Wire Mesh Grips in a Directional Drilling application be limited to relatively short pulls. The friction or suction caused by mud and water around the ducting being installed drastically increases the load of the pull and may cause the grip to break loose. It is also recommended that some form of Duct tape be used to assist in initiating the grip onto the ducting especially where longer pulls are expected.
