Instrument cable tray clamps

Instrument cable tray clamps are specialized supports designed to secure instrumentation cables and tubing within cable trays, ensuring organized, safe, and stable installations.

Overview

Instrument cable tray clamps are used to secure and support instrumentation cables, tubing, and hoses within cable trays or channel systems. They help prevent chafing, damage, and disorganization while maintaining proper routing and spacing for instrumentation lines . These clamps are essential in industrial, offshore, onshore, and commercial installations where reliable cable management is critical .

Types of Clamps

• Single Clamps: Hold a single cable or tube securely in place within a tray or channel .
• Duplex Clamps: Designed to hold two parallel cables or tubes, often used for paired instrumentation lines .
• Yoke Clamps: Provide additional stability for larger or heavier tubing assemblies .
• Gang Clamps: Allow multiple cables or tubes to be secured together in a compact arrangement .
• Heavy-Duty Hold-Down Clamps: Used for fastening cable trays to beams or C-channels, often with copper alloy or iron construction for high load capacity .

Materials and Finishes

Clamps are typically made from stainless steel, galvanized steel, aluminum, or copper alloys, depending on environmental conditions and load requirements . Some clamps feature tin plating or zinc plating for corrosion resistance . Cushioned or lined clamps are available to minimize vibration and protect delicate instrumentation tubing .

Installation and Compatibility

• Clamps are designed to fit perforated cable trays, channel trays, or STRUT framing systems .
• Many clamps include hardware for direct attachment, reducing field labor and eliminating the need for drilling in some cases .
• Adjustable clamps and modular support systems allow for horizontal or vertical mounting on pipes, beams, or structural supports .
• Load capacities vary; for example, some heavy-duty clamps can support up to 400 lbs per clamp .

Applications

Instrument cable tray clamps are widely used in:

• Oil & Gas, Offshore, and Marine Installations
• Industrial Process Plants
• Commercial Electrical and Instrumentation Systems
• Shipbuilding and Rig Installations They ensure organized routing, secure attachment, and compliance with safety and engineering standards .

Summary

Choosing the right instrument cable tray clamp depends on cable/tube diameter, load requirements, environmental conditions, and tray type. Options include single, duplex, yoke, gang, and heavy-duty hold-down clamps, made from durable materials with corrosion-resistant finishes. Proper selection and installation improve system reliability, reduce maintenance, and protect instrumentation lines from damage.
