Cable Tray Insert Liner


SKU LV-18-30-100

Our Cable Tray Insert Liner is designed to provide a solid surface for the bottom of cable trays. This helps to prevent the snagging of cables and wiring. The high density polyethylene plastic (HDPE) provides a smooth surface which allows for the easy passing of cabling and is flexible, allowing the plastic to conform to various tray features. The material is easily cut with a utility knife which makes customizing the liner to various cutouts and openings simple and straight forward. 

Available in both 30 mil and 40 mil thicknesses, our cable tray liner is available in a wide variety of roll widths ranging from 18” - 48” and in 100’ roll lengths. Our liner is made in the USA and ships from Kansas City.

*The widest HDPE roll that we offer is currently 5’ (60 inches).

Please note that we are unable to provide custom roll lengths.

Elevating Cable Management: The Benefits of Cable Tray Insert Liners

Effective cable management is a critical aspect of modern electrical installations, influencing not only the longevity of the cable system but also its safety and efficiency. Cable trays are a popular solution for organizing and protecting wires and cables across various industries. To further enhance these benefits, cable tray insert liners are used to provide an additional layer of protection. This blog post delves into the benefits, features, and applications of cable tray insert liners, showcasing why they are an indispensable part of advanced cable management systems.

What are Cable Tray Insert Liners?

Cable tray insert liners are designed to fit snugly within cable trays, providing a protective layer that shields cables from potential damage caused by contact with the tray's material, usually metal. These liners are typically made from durable materials such as polyethylene, PVC, or rubber, chosen for their protective qualities and resilience to environmental factors.

Key Features:

Durability: Resistant to wear, tear, and environmental damage, including chemicals and extreme temperatures.
Smooth Surface: Reduces friction and prevents the abrasion of cables.
Electrical Insulation: Offers additional electrical isolation to prevent faults and short circuits.
Customizability: Available in various sizes and can be custom-cut to fit any tray configuration.

Benefits of Using Cable Tray Insert Liners

The integration of insert liners in cable tray systems provides several significant advantages:

Enhanced Cable Protection

The primary role of cable tray insert liners is to provide a smooth surface that minimizes the risk of physical damage to cables, such as cuts, abrasions, or the wearing away of insulation. This is particularly important in industrial settings where cables are exposed to rough handling or environmental hazards.

Increased Safety

Cable tray insert liners enhance safety by adding an extra layer of electrical insulation. This is crucial in environments where there is a high risk of electrical faults, potentially leading to fires or equipment damage. The liners help mitigate these risks, contributing to a safer installation overall.

Simplified Maintenance

With their easy-to-clean surfaces, cable tray insert liners simplify maintenance tasks. They prevent dirt, debris, and smaller particles from accumulating in the tray, which can degrade cables over time. Cleaning is more straightforward, reducing maintenance time and costs.

Improved Installation Efficiency

Insert liners are designed for easy installation, often simply laying inside the tray or snapping into place without the need for additional fasteners. This ease of installation can significantly reduce labor costs and time, making it a cost-effective solution for large-scale projects.

Applications of Cable Tray Insert Liners

Cable tray insert liners are versatile and find applications across a broad range of environments:

Industrial Plants: Protects cables from the harsh conditions of manufacturing and processing facilities.
Commercial Buildings: Provides a neater appearance and added safety in areas where cables are exposed.
Data Centers: Essential for protecting sensitive data cables from physical damage and electrical interference.
Healthcare Facilities: Helps maintain high standards of safety and cleanliness, crucial in medical settings.


Cable tray insert liners are a crucial component for any sophisticated cable management system, providing enhanced protection, increased safety, and ease of maintenance. Whether for a new construction project or upgrading an existing system, considering the integration of cable tray insert liners is a wise and beneficial choice. By ensuring the protection and efficiency of cable installations, these liners play a pivotal role in maintaining the reliability and functionality of critical infrastructure.
