Super Deluxe Pullers

Short Answer: A Super Deluxe Duct Puller is used to grip the inside of duct and pull it during conduit or duct installation.

Correct use: The puller is inserted into the duct and tightened so the internal sealing surfaces expand and grip from the inside. This creates a secure pull point for installing duct through a bore or pathway without crushing the outside of the duct.

Technical details: The internal sealing design helps the puller seat securely against the inside wall of the duct, creating a watertight-style seal and consistent grip. The assembly can be disassembled by hand for cleaning and field maintenance, and includes a high-tensile drop-forged eyebolt for pull loads.

Incorrect use includes: Using the puller in duct sizes outside its rated I.D. range or pulling on damaged duct. Incorrect use can introduce greater risk of slippage or duct damage.

Short Answer: Super Deluxe Duct Pullers are compatible with duct sizes based on the duct's inside diameter (I.D.) range for the selected puller size.

Correct use: Choose the puller model that matches your duct's inside diameter so the internal sealing surfaces can expand correctly and hold securely. Matching to I.D. is the key factor for safe pull performance.

Technical details: Each puller size has a defined I.D. range it is designed to seal against. Using the correct range improves grip consistency and helps prevent slippage during pull.

Incorrect use includes: Selecting a puller that is too small or too large for the duct I.D. Incorrect use can introduce greater risk of poor sealing, slippage, or duct deformation.

Short Answer: Super Deluxe Duct Pullers can be used in any ground condition as long as the bore is properly prepared for duct installation.

Correct use: Ground conditions are addressed during drilling and reaming. Once the bore is sized correctly and cleaned, the puller provides a secure internal grip for pulling duct in dirt, clay, mixed ground, and other formations.

Technical details: The puller's performance depends on duct I.D. match and a stable bore path rather than soil type. Bore diameter, cleanliness, and pull forces are the main factors affecting installation success.

Incorrect use includes: Pulling duct through an undersized or unstable bore or exceeding pull limits for the duct. Incorrect use can introduce greater risk of high pull loads, slippage, or duct damage.

Short Answer: Eye swivels and duct pullers serve different purposes during pullback and are not interchangeable.

Correct use: An eye swivel is used when pulling product that already has an external pulling eye or adapter and needs to rotate independently of the drill string. A duct puller is used when the product must be gripped internally, such as conduit or duct without an external pulling attachment.

Technical details: Eye swivels manage rotation and help prevent product twist, while duct pullers create an internal mechanical grip inside the product itself. The correct choice depends on whether the product has an external pull point or requires internal engagement.

Incorrect use includes: Using an eye swivel when no external pull point exists or attempting to pull duct without proper internal grip. Incorrect use can introduce greater risk of slippage, product damage, or installation failure.

Short Answer: Duct pullers must be sized by inside diameter (I.D.) because they grip from inside the duct, not the outside.

Correct use: Always select a duct puller based on the actual inside diameter of the duct so the internal jaws or sealing surfaces can expand properly and distribute load evenly during pullback. Nominal duct size alone does not account for wall thickness or SDR variation.

Technical details: Different SDR ratings change the duct's wall thickness, which directly affects I.D. A puller sized by nominal diameter may not grip correctly if the I.D. falls outside the puller's working range.

Incorrect use includes: Choosing a puller based only on nominal duct size without verifying I.D. Incorrect use can introduce greater risk of poor grip, slippage, or duct damage.
