How to pull the cable out of the cable tray

Use a cable tray side dropout or a dropout plate to safely route cables out of the side of a cable tray while maintaining proper bend radius and protecting the cable.Using Side Dropouts

Side dropouts are accessories designed specifically for exiting cables from the side of a wire mesh or ladder-type cable tray. Popular options include:

• BDO (Basic Drop Out): 4” wide with snap-in mounting tabs, allowing cables to drop out without additional hardware .
• SDO (Slotted Drop Out): Available in 6” and 12” widths, with slots for cable tie attachment, suitable for side or end exits .
• UDO (Universal Drop Out): Available in 8”, 12”, 18”, and 24” widths, ideal for dropping cables over the side of a tray .
• Cablofil Center Drop Out (CDO): Designed for high-capacity data centers, it snaps in place, supports heavy copper and fiber optic bundles, and can be repositioned as needed . These dropouts maintain the proper bend radius, prevent sharp bends, and reduce the risk of cable damage.

Using Dropout Plates

A dropout plate is another method to exit cables safely:

• Place the plate between rungs or at the end of the tray.
• It provides a smooth, protected exit point, reducing abrasion and strain on the cable .
• Avoid exiting cables directly over the side without a dropout plate, as this can cause sharp bends and potential conductor damage .

Important Considerations

• Do not cut or notch the tray side rails unless specifically allowed by the manufacturer, as this can compromise structural integrity .
• Ensure that any attachment or modification is listed for the intended purpose and complies with electrical codes.
• Use cable ties or other securing methods to keep cables organized and prevent sagging or stress at the exit point. By using the appropriate side dropout or dropout plate, you can safely route cables out of the side of a cable tray while protecting both the cable and the tray structure .
