Cable tray protective sleeves are designed to protect cables at tray penetrations and bends, with specifications varying by type, material, and radius. Types and Applications1.

Exit and Radius Limiter Sleeves

Used where cables exit or enter trays, or at tees, crosses, and elbows. Example: Cablofil CableXit100PG sleeve protects cables and eases strain with a 2-inch radius. Installation: Can attach via built-in tabs or bolt connections.

Material: Corrosion-resistant galvanized steel. 2.

Wall and Penetration Sleeves

Fabricated steel sleeves provide rigid support for cable trays at wall or floor penetrations. Can include firestop products for UL-classified fire-rated systems. Outdoor conversion kits make sleeves weather-resistant.

Steel ladder tray sleeves also serve as equipment grounding conductors per NEC 392. 60. 3.

Flexible Braided or Spiral Sleeves

Protect cables from abrasion, sharp edges, and chafing. Materials: Natural polyethylene, weatherable black polyethylene, or flame-retardant versions. Operating temperature: -75°C to 125°C.

Features: Lightweight, flexible, resistant to chemicals, UV, and fuels. Installation: Easily cut with a hot knife to seal ends; self-wrapping versions are quick to install and remove.

Dimensions and Considerations

Radius: Protective sleeves often specify a minimum bend radius (e.g., 2 inches for Cablofil CableXit100PG) to prevent cable strain. Diameter: Flexible braided sleeves accommodate a range of bundle diameters; exact sizing depends on cable bundle size. Length: Wall and penetration sleeves are fabricated to match wall thickness or penetration depth; lengths vary by application.

Material Thickness: Steel sleeves are typically galvanized for corrosion resistance; flexible sleeves are thin but durable. Key FeaturesFire-rated options available for wall/floor penetrations. Corrosion-resistant finishes for indoor and outdoor use.

Flexible sleeves allow bundling and protection inside cabinets or enclosures. Some sleeves are self-wrapping for easy installation and removal. When selecting a protective sleeve, consider cable bundle size, bend radius, environmental exposure, and fire-rating requirements to ensure compliance with safety standards and proper cable protection.
