UTH10 is a structural attachment used in fire sprinkler sway brace systems. It connects the brace pipe to the building structure, providing a fixed point that resists lateral and longitudinal movement during seismic events. When combined with a compatible structural fitting and bracing pipe, it forms a complete assembly that meets NFPA 13 standards.
The component is designed with practicality in mind. One size accommodates braced pipe up to 8 inches, which covers most common pipe schedules including Sch 10, Sch 40, GB/T 3091 and JIS G3454. This eliminates the need to stock multiple sizes for different pipe diameters, simplifying inventory management for contractors and distributors.
The UTH10 is cast from ductile iron QT450, a material known for its strength and impact resistance. Unlike grey iron, ductile iron offers better elongation and fatigue resistance, which matters in applications where vibration and seismic forces are present.
The electro-galvanized finish adds a layer of corrosion protection. It is not meant for continuous outdoor exposure but performs well in typical indoor environments, mechanical rooms, parking garages and sheltered areas. For projects with stricter corrosion requirements, we recommend consulting with our technical team for alternative finishing options.

When used with 1-inch SCH40 brace pipe, the UTH10 supports a maximum design load of 1,885 lbs (8.38 kN). This rating is verified under UL certification, giving engineers and specifiers confidence in its performance.
The attachment is also CE certified, meeting the market access requirements for the European Union. The UL certification mark is clearly displayed on the product body for easy inspection.
Installation follows a straightforward sequence. The base part is first secured to the building structure using M12x60 bolts. Recommended installation torque is between 50 and 65 N·M. A 1-inch SCH40 brace pipe is then connected to the base. The final step involves tightening the shear bolt until the head breaks off. This break-off feature confirms that correct torque has been reached, eliminating the need for torque wrenches during field installation.
The shear bolt design also serves as a tamper-evident indicator. Once the bolt head is sheared off, inspectors can quickly verify that the connection has been properly tightened.
UTH10 is suitable for a wide range of building types where fire sprinkler systems require seismic bracing. Typical applications include office towers, manufacturing facilities, school buildings, hospital campuses, data centers and multi-family residential complexes.
In seismic zones, building codes often require sprinkler piping to be braced against earthquake-induced movement. The UTH10 addresses this requirement by providing a strong, code-compliant connection point between the piping system and the structural frame.
The combination of dual certifications, broad pipe compatibility and simple installation makes the UTH10 a practical choice for both new construction and retrofit projects. The ductile iron construction provides durability without unnecessary weight, and the shear bolt mechanism reduces installation time and errors.
We have been manufacturing bracing components since 2016, with quality control procedures in place for every batch. Load test documentation and certificates of conformity are available upon request for project submittal purposes.
1. What pipe schedules does the UTH10 work with?
It fits Sch 10, Sch 40, GB/T 3091 and JIS G3454 pipes up to 8 inches. One size covers all these standards.
2. Is the UTH10 UL listed?
Yes, it carries UL certification with the mark clearly displayed on the product body. CE certification is also available, meeting EU market access requirements.
3. What is the torque spec for the shear bolt?
Tighten until the bolt head breaks off. This design confirms correct torque without needing a torque wrench in the field.
4. Can this be used outdoors?
The electro-galvanized finish handles indoor and sheltered environments well. For continuous outdoor exposure, we would suggest looking at alternative finishes.
5. Do you provide test reports for project submittals?
Yes, load test documentation and certificates of conformity are available upon request.
