Cable tray spring washers

Spring washers are used in cable tray systems to maintain tension, prevent loosening, and ensure secure connections in wire mesh or basket trays.Purpose and Function

Spring washers, also known as lock washers, are designed to prevent nuts and bolts from loosening due to vibration or thermal expansion in cable tray installations. They are commonly used in wire mesh trays, basket trays, and other cable management systems to maintain structural integrity and ensure that cable pathways remain secure over time .

Types and Applications

• Splice Washer Kits: These kits include washers, studs, and nuts to connect sections of cable trays, allowing for straight runs, bends, or intersections. Examples include Eaton's B-Line Flextray Washer Splice Kit and Cablofil's Splice Washer Kit-Ez .
• Wire Basket Tray Washer Supports: These washers provide continuous support along the tray, helping to anchor trays at 90-degree angles or intersections while keeping the installation visually clean and structurally sound .
• Clamp Connectors with Washers: Used for joining bent or curved wire mesh trays, these washers work with nut and bolt assemblies to secure complex tray runs .

Installation Considerations

• Ensure washers are compatible with the tray type and size (e.g., 4 in, 6 in, 8 in, 12 in, etc.), .
• Follow manufacturer instructions for torque specifications to prevent over-tightening or under-tightening, which could compromise tray stability .
• Use reinforced or electrogalvanized washers in environments prone to corrosion or heavy loads to enhance durability .

Sourcing

Spring washers and splice kits for cable trays are available from suppliers such as Eaton, nVent CADDY, Cablofil, and Grainger, with options ranging from small packs (30–50 pieces) to full installation kits for commercial projects . By selecting the appropriate spring washer and following proper installation practices, cable tray systems can maintain long-term stability, safety, and performance in commercial and industrial environments.
