Installation and Price of New Type Elbows for Cable Trays

New type cable tray elbows are designed for faster, secure installation with pre-punched holes and modular splices, and pricing varies by material, size, and supplier.

Installation Features

Horizontal and vertical elbows for cable trays are engineered to simplify cable routing and reduce labor: Pre-punched holes allow cables to be attached without drilling, speeding up installation and reducing labor costs (Atkore). Modular splice plates are included with elbows, tees, and crosses, enabling secure connections with minimal hardware. For example, horizontal elbows often come with one standard splice plate, while tees and crosses include multiple connectors at no extra charge.

Aluminum I-beam designs provide structural strength while minimizing tray width, allowing smooth transitions between straight sections and elbows. Only four bolts per splice are typically required, reducing hardware needs by 50% and enabling installation up to 30% faster than standard trays (Legrand Itray/90HB). Vertical inside elbows allow upward cable routing, with rail heights from 4" to 7", widths from 6" to 36", and radii from 12" to 36", suitable for ladder or solid-bottom trays.

Material options include aluminum alloys, galvanized steel, stainless steel, and FRP, providing corrosion resistance and strength for industrial or commercial applications.

Pricing Considerations

Pricing depends on tray width, elbow angle, bend radius, material, and supplier. For example, Legrand Itray elbows are available in 12" tray width, 90° angle, and 12" bend radius, with pricing accessible through supplier portals like EECOonline. Many suppliers, including Graybar, provide ZIP code-based pricing, which allows for location-specific cost estimates for elbows and other fittings.

Custom fabrication is available for projects requiring non-standard sizes or materials, which may affect cost.

Summary

New type elbows for cable trays are designed to reduce installation time, minimize hardware, and provide flexible routing for both horizontal and vertical applications. Aluminum and steel options are common, with pre-punched holes and modular splices simplifying installation. Pricing varies by material, size, and supplier, and can often be obtained through online portals or by contacting distributors directly.

For large projects, considering installation efficiency and material choice can significantly impact overall project cost and labor requirements.
