The slant side of a cable tray refers to the angled or inclined side rail, typically found on ladder-type or I-beam cable trays, which guides cables and supports structural loads.

Understanding the Slant Side

In ladder-type cable trays, the side rails are the longitudinal members running along the tray's length, connected by transverse rungs that support the cables . The slant side is the portion of the side rail that is angled or tapered, often designed to facilitate cable entry, exit, or to accommodate fittings such as horizontal or vertical bends . In I-beam style trays, the slant side may also refer to the inclined flange of the I-beam, which provides additional strength and allows splice plates or accessories to be attached easily .

Function and Importance

• Cable guidance: The slant side helps direct cables smoothly into the tray, reducing stress and maintaining proper bending radii .
• Structural support: Angled side rails increase the tray's load-bearing capacity by distributing weight more efficiently along the tray length .
• Accessory attachment: Many modern trays, like Eaton's B-Line KwikRail, feature pre-punched slant sides for easy installation of splice plates, covers, or clamps without drilling .
• Fitting integration: Slant sides are particularly important at bends, risers, or reducers, where the tray changes direction or width, ensuring cables remain supported and organized .

Practical Considerations

When installing or selecting a cable tray, it is important to identify the slant side to:

• Maintain proper cable bending radii and avoid damage.
• Ensure compatibility with splice plates, covers, and other accessories.
• Optimize load distribution and minimize deflection, especially in long spans . In summary, the slant side is the angled portion of the tray's side rail that plays a critical role in cable management, structural integrity, and accessory attachment in both ladder and I-beam cable tray systems .
