Cable tray accessories length table

Cable tray accessories are manufactured in standardized lengths to ensure compatibility with straight sections and fittings, typically ranging from 250 mm to 3000 mm depending on type and application.

Standard Lengths of Common Accessories

Cable tray accessories are designed to match the straight tray sections and maintain system continuity. Typical lengths include: Elbows (Horizontal/Vertical): Usually 250 mm to 500 mm for light and medium duty trays, adjustable in some systems to fit angles precisely. Reducers: Standard lengths range from 250 mm to 500 mm, depending on the width reduction required.

Tees and Crosses: Typically 300 mm to 600 mm, allowing smooth branching of cable runs. Risers (Vertical Sections): Adjustable risers often slide inside the tray and can extend to 1000 mm or more, depending on installation height. Joint Connectors and Covers: Usually 100 mm to 300 mm, designed to bridge tray sections or secure cables.

Notes on Material and FinishAccessories are available in galvanized steel, stainless steel, or powder-coated finishes to suit environmental conditions. Lengths may vary slightly depending on tray width, height, and duty rating (light, medium, heavy, extra heavy) to maintain structural integrity and NEC/NEMA compliance.

Installation Considerations

Adjustable fittings like Swifts® risers and flat ends allow installers to modify lengths on-site for precise alignment. Accessories are designed to fit standard tray widths (commonly 100 mm to 600 mm) and heights (50 mm to 150 mm), ensuring compatibility across the system. Fast-fit systems such as Swiftclip reduce the need for exact pre-cut lengths, allowing two clips per joint to secure sections quickly.
