90-degree bend on the side of the cable tray

A 90-degree side bend in a cable tray allows the tray to change direction horizontally or vertically while maintaining cable support and continuity.Types of 90-Degree BendsHorizontal and vertical elbows are standard fittings used to create 90-degree turns in cable tray systems. They are available for various tray classes:Class 1: For NEMA 12B and 12C trays, with 1-1/8″ side rail flanges and 4-hole splice plates.Class 2: For NEMA 20A, 20B, and 20C trays, with 2″ side rail flanges and 4-hole splice plates.Class 3 and 4: For heavier-duty trays, with wider flanges and 8-hole splice plates for added strength . Wire mesh cable trays also offer 90-degree bend kits that can accommodate one or two bends per kit. These kits include hardware and a slotted design to fit various tray sizes, simplifying installation and alignment on-site . Mesh cable tray bends are available in pre-fabricated 90° horizontal configurations, suitable for trays with specific side heights, such as 105 mm .Installation ConsiderationsMeasure and mark the bending points along the straight tray to ensure accurate alignment .Use offset calculations if the bend must navigate around obstacles like columns, ducts, or pipes. Tools and calculators can help determine the required sloped section length and horizontal run .Secure splice plates or hardware according to the tray class to maintain structural integrity and support the cable load .Wire mesh trays allow on-site adjustments, providing flexibility for complex routing and faster installation .Practical TipsAlways check compatibility between the bend fitting and the tray type.For tight spaces, consider pre-fabricated bends or adjustable kits to reduce on-site modifications.Follow UL classification and RoHS compliance for safety and regulatory adherence .Video tutorials can provide step-by-step guidance for making precise 90-degree bends if you are new to cable tray installation . Using the correct 90-degree side bend ensures smooth cable routing, maintains mechanical support, and allows for safe, efficient installation in both industrial and commercial environments.
