The Silver Pull-it Bundled Micro-duct Puller uses a patented design to improve the security, peace of mind, and production rate when installing bundled micro-duct. The simple yet reliable design provides a solution for many different bundle configurations. If you choose one of the inserts, it can widen your flexibility to even more configurations and sizes.
- Many size configurations unique to each micro-duct configuration
- Stainless screw connection with crosshatched security
- A machined internal spacer contour that snugly fits the outer contour of the bundled micro-duct
- Carry a single puller, rather than many mesh-grip pullers that wear out.

FREQUENTLY ASKED QUESTIONS
Short Answer: Silver Pull-It pullers are used to securely pull bundled micro-duct during HDD installations.
Correct use: The Silver Pull-It is designed specifically for bundled micro-duct configurations, allowing the installer to grip and pull multiple ducts at once during pullback.
Technical details: The puller uses stainless steel fasteners driven into the micro-duct bundle in a crosshatched pattern to provide a secure internal grip without crushing the ducts. Its modular design allows one puller to cover multiple bundle layouts using removable inserts.
Incorrect use includes: Using the puller on single large-diameter pipe or non-micro-duct products. Incorrect use can introduce greater risk of slippage, safety risks, or duct damage.
Short Answer: Silver Pull-It pullers are compatible with a wide range of bundled micro-duct configurations.
Correct use: The puller can be configured to match common micro-duct bundle layouts by using the appropriate internal spacers. This allows one puller body to adapt to different bundle sizes and duct counts.
Technical details: Compatibility is determined by the internal spacer selection and fastener placement rather than the puller body itself. Spacer inserts are used to match the internal profile of the micro-duct bundle for a secure, centered grip.
Incorrect use includes: Attempting to pull bundles without the correct spacer configuration or using the puller without properly installed fasteners. Incorrect use can introduce greater risk of uneven loading, loss of product downhole, or duct deformation.
Short Answer: Silver Pull-It pullers can be used in any ground condition once the bore is properly prepared.
Correct use: Ground conditions are addressed during drilling and reaming, not during pullback. The Silver Pull-It mini micro-duct puller is used after a clean, stable bore has been created and is suitable for micro-duct installation in dirt, clay, mixed ground, and other formations.
Technical details: The puller's role is to securely grip the micro-duct bundle during pullback. Bore stability, diameter, and cleanliness are the primary factors affecting installation success.
Incorrect use includes: Using the puller in an improperly sized or unstable bore. Incorrect use can introduce greater risk of increased pull forces 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.
