  • The urethane clamp body helps protect the cable jacket from surface damage
  • Suitable for ADSS and OPGW cable downlead management
  • Secure holding performance without crushing cable fibers
  • Compatible with curved and flat mounting surfaces
  • Supports a broad range of cable diameters
  • Galvanized steel hardware for improved outdoor durability
  • Easy installation on wood poles and similar structures
  • Designed for structured cable routing from pole top to splice point
  • Available in multiple groove sizes for accurate cable fit
  • Performs reliably in wide temperature ranges

The Urethane Downlead Clamp is designed to secure and guide ADSS and OPGW cables along poles or structures while minimizing pressure damage to the cable jacket. Built with durable urethane rubber halves and galvanized steel mounting hardware, this clamp provides a stable hold and controlled cable routing for downlead sections in telecom and power line networks.

Its compressive elastomer contact surface cushions the cable and helps protect the outer sheath from abrasion during long-term outdoor use. The clamp is suitable for curved and flat mounting surfaces and can be installed on wood poles and similar structures using standard field hardware. With multiple groove options available, the TX-DUC series supports a wide range of cable diameters, making it a practical choice for fiber routing from pole top to splice location or other fixed cable points.

Designed for reliable performance in demanding environments, the clamp resists temperature variation, outdoor exposure, and general mechanical wear. It is a dependable solution for organized cable management where secure holding and sheath protection are both essential.

International Standard Compliance

The TX-DUC Urethane Downlead Clamp is manufactured according to applicable quality and material control practices for utility and telecom accessories.

  • ISO 9001:2015 quality management system-based production
  • RoHS-compliant material options available
  • ISO 4892.3:1994 reference for UV resistance testing basis
  • Material and dimensional control aligned with general utility hardware manufacturing requirements

Construction & Materials

The TX-DUC clamp is built for secure cable support and long-term field performance.

Main construction includes:

  • Clamp body: Urethane elastomer
  • Protective contact section: Compressive urethane rubber halves
  • Mounting hardware: Galvanized steel
  • Lag screw: 1/2″ × 4″ galvanized steel
  • Washers: Square curved washer and standard round washer set

The urethane body helps distribute compressive force more evenly around the cable, reducing the risk of jacket wear while maintaining adequate holding force for downlead applications.

Installation Guide:

  1. Confirm the cable outside diameter and select the correct TX-DUC groove size.
  2. Mark the desired installation location on the wood pole or structure.
  3. Ensure the mounting surface is clean and suitable for secure fastening.
  4. Place the urethane clamp halves around the cable carefully.
  5. Position the clamp assembly against the structure.
  6. Insert the galvanized lag screw with the required washers.
  7. Tighten the hardware evenly until the clamp holds the cable firmly.
  8. Do not overtighten, as the cable should be secure without unnecessary compression.
  9. Repeat installation at the required spacing along the cable route.
  10. Check final cable alignment and holding stability.

Installation Note:
Downlead clamps are generally installed to guide the cable from the top of the pole or structure to the splice or transition point while maintaining safe spacing and bend control.
