In cable tray and mounting systems, "FH" typically refers to a type of clamp or mounting accessory designed for securing cables or conduits to rails or plates.

Explanation

In the context of cable trays and cable management, FH is used to designate specific clamp or holder types. For example, ABB and PMA systems use FH clamps that can be mounted on a PMA FHS rail or directly on a plate. These clamps allow for secure attachment of conduits or cables while enabling spacing adjustments and easy installation of adjacent clamps for conduit placement . Key characteristics of FH clamps include:

• Compatibility with standard rails (e.g., FHS rails) or direct plate mounting.
• Adjustable spacing to accommodate multiple conduits or cables.
• Snap-closure design for quick installation and secure holding.
• Use in professional cable management systems to maintain organization and safety.

Related Uses

• In some electrical contexts, "FH" can also appear in breaker designations (e.g., FA vs FH breakers), where it identifies a specific series or type of device . However, in cable tray systems, it is primarily associated with mounting hardware rather than electrical components.
• FH is part of a broader system of standardized accessories that ensure proper airflow, spacing, and mechanical support for cables in industrial or commercial installations .

Summary

When you see "FH" in cable tray documentation or product catalogs, it refers to a clamp or holder type used for securing cables or conduits, often compatible with rails or plates, and designed for efficient, adjustable, and safe cable management . This designation helps installers quickly identify the correct mounting accessory for a given cable tray setup.
