Description

The Themis (2BCHT) two-bolt high-temperature single cable cleat is a heavy-duty, fire-rated solution engineered for the secure retention of single cables in critical electrical installations. Tested to IEC 61914 (Cable Cleats for Electrical Installations), it ensures cables are firmly secured without damage or deformation.

Fire-Rated Protection for Critical Circuits

The Themis (2BCHT) cable cleat is purpose-built for use with LSZH and fire performance cables, maintaining support and system integrity during prolonged high-temperature fire conditions. It plays a key role in protecting life safety systems and evacuation routes, ensuring continued operation during emergencies.

High Strength Design for Maximum Retention

Featuring a patent-pending twin arc internal design, Themis cleats deliver excellent cable retention, significantly reducing both axial and lateral movement under fault or high-temperature fire conditions. The two-bolt fixing design enhances stability and load performance, making it ideal for larger cable diameters and demanding installations.

Built for Harsh Environments

Manufactured from marine-grade 316L stainless steel, the Themis cleat offers exceptional resistance to corrosion, making it suitable for indoor, outdoor and industrial environments.

With an operating temperature range of -60°C to +250°C and fire resistance tested up to 1,200°C, it is designed for high-temperature, fire-rated applications.

Sizes & Installation

Choose the correct Themis cleat by matching the cable outer diameter, installation method and required performance rating for the circuit.
The CMP Themis cleat is available in 6 sizes, accommodating cable diameters from 38mm to 109mm, providing efficient coverage with fewer product variations.
Each cleat features two M10 or M12 clearance holes, allowing installation with either M10 or M12 fasteners. The cleats are also stackable where required, offering a flexible and reliable cable management solution for demanding life safety and fire-rated installations.
For best results, confirm availability and lead times when ordering, and request technical support for sizing and selection where required.
