Methods for fixing cable trays with clips

Cable tray clips are essential for securing trays and covers, with options ranging from snap-on stainless steel clips to heavy-duty galvanised steel clips for durable, corrosion-resistant installation.

Types of Cable Tray Clips

1. Snap-On Clips: These clips are designed to quickly secure cable tray covers without welding or special tools. The main body fits inside the tray while a smaller part grips the cover, creating a stable connection using simple pressure. They are often made from 304 stainless steel, offering rust and corrosion resistance, and are reusable for maintenance purposes. Ideal for light-duty applications or areas with minimal vibration . 2. Screw or Bolt Clips: Some clips require screws to tighten the grip, providing a more permanent hold. These are suitable for environments where vibration or movement could loosen snap-on clips. Materials are typically stainless steel for durability . 3. Heavy-Duty Lid Clips: For 50mm deep heavy-duty trays, hot-dip galvanised (HDG) steel clips are recommended. They provide long-term corrosion resistance and strength, with 4–6 clips per lid section suggested for secure fastening. These are ideal for both internal and external installations . 4. Hanging Clips: Used to suspend trays from threaded rods (1/4", 3/8", or 1/2"), these clips attach to the sides of the tray and require nuts and washers for secure installation. Zinc-plated versions offer corrosion resistance and are suitable for wire mesh trays .

Installation Tips

• Spacing: Follow manufacturer recommendations for clip spacing; heavy-duty lids typically need 4–6 clips per section .
• Material Selection: Use stainless steel for indoor/outdoor environments prone to moisture, and HDG steel for heavy-duty or outdoor applications .
• Tools: Snap-on clips often require no tools, while screw or bolt clips need appropriate screwdrivers or wrenches. Hanging clips require threaded rods, nuts, and washers .
• Maintenance: Reusable clips allow easy removal of covers for cable access, reducing downtime during inspections or upgrades .

Summary

Choosing the right clip depends on tray type, load, environment, and maintenance needs. Snap-on stainless steel clips are quick and reusable for light-duty applications, screw-tightened clips provide a more permanent hold, and heavy-duty HDG clips ensure secure fastening for deep or outdoor trays. Proper installation ensures safety, prevents cable damage, and maintains structural integrity of the cable management system .
