Reverse Thread Couplings | Ribbed Wall | Aluminum
US Coupler Aluminum Reverse Threaded Couplers are specifically designed for SDR ducts with ribbed walls, providing a strong, durable, and easy-to-install solution. These couplers feature sharp buttress type threads that deliver high pulling load capacities, meeting or exceeding the Bellcore tensile standard of 1000 lbs. Originally developed by Cabletec, now part of US Coupler, these couplings excel in challenging environments such as manholes, direct burial, and aerial installations.
Key Features:
- High Pulling Load Capacity: The sharp buttress threads are engineered to withstand significant pulling forces, ensuring that these couplers meet the rigorous Bellcore tensile standards for robust and reliable performance.
- Ease of Installation: Featuring a wide, eight-pitch thread angle, these couplers require fewer revolutions for installation, reducing labor time. The long chamfered lead-in allows for straight, easy starting during installation.
- Versatile Application: Ideal for ribbed wall SDR ducts, these couplers are suitable for use in manholes, direct burial, aerial, and other applications where an air or watertight connection is not required.
Important Usage Information:
These Aluminum Reverse Threaded Couplers should NOT be installed in the following conditions:
- Wet environments or where the coupling may be submerged in water.
- Environments with strong acidic or alkaline conditions outside the pH range of 4 to 8.
- Near saltwater or where there is direct exposure to road salt runoff.
- Embedded in concrete or cement-stabilized sand.
Applications: Perfect for SDR duct systems with ribbed walls in various installation environments requiring high tensile strength and quick installation.
