Cable Tray Insert Plastic


SKU LV-18-30-100

Our Cable Tray Insert Plastic is designed to provide a solid surface for the bottom of wire 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.

Understanding Cable Tray Insert Plastic: Enhancements for Cable Management Systems

Cable management is a critical aspect of modern infrastructure, ensuring safety, organization, and efficiency in the routing of electrical cables. Cable trays are an integral component of this system, providing support and organization for a myriad of cable types. To enhance the functionality and durability of these systems, cable tray insert plastic plays a pivotal role. This blog post explores what cable tray insert plastic is, its benefits, and why it’s essential for effective cable management.

What is Cable Tray Insert Plastic?

Cable tray insert plastic refers to the plastic liners or covers that are used within cable trays. These inserts are designed to provide a smooth, protective layer inside metal or other types of cable trays. Typically made from high-quality, durable plastics such as polyvinyl chloride (PVC) or polyethylene (PE), these inserts are tailored to fit the contours of the trays, ensuring a snug and secure fit.

Key Features:

Durability: Resistant to various chemicals, physical impacts, and extreme temperatures.
Flexibility: Easily customizable to fit various tray designs and configurations.
Corrosion Resistance: Offers protection against environmental factors that can corrode metal trays.
Electrical Insulation: Provides an additional layer of insulation, enhancing safety.

Benefits of Using Cable Tray Insert Plastic

Incorporating plastic inserts into cable tray systems offers several advantages:

Protection from Damage

Cable trays are often made from materials like steel, which, while durable, can have sharp edges that might damage cables over time. Cable tray inserts provide a smooth surface that minimizes this risk, safeguarding the cables from abrasions and cuts.

Enhanced Safety

By adding an insulative barrier, these inserts reduce the risk of electrical faults and fires, which can be triggered by damaged insulation or exposed wires. This feature is particularly crucial in industries where cable integrity is paramount for safety and operational reliability.

Ease of Installation and Maintenance

Plastic inserts can be easily snapped or slid into place within the trays, making installation straightforward. They are also easy to clean and require minimal maintenance, reducing downtime and maintenance costs.

Applications of Cable Tray Insert Plastic

Cable tray inserts are versatile and find applications across various industries:

Industrial Facilities: Protects cables from the harsh conditions often found in manufacturing and processing plants.
Commercial Buildings: Enhances safety and aesthetics in environments where appearance is important.
Data Centers: Ensures the high reliability required for data communication cables.
Healthcare Facilities: Maintains stringent safety standards necessary for sensitive environments.


Cable tray insert plastic is more than just a protective accessory; it is a crucial component that enhances the longevity and functionality of cable tray systems. By providing essential protection, safety, and flexibility, these inserts ensure that cable management systems meet both current and future infrastructure demands. For businesses looking to optimize their cable management, investing in high-quality cable tray insert plastic is a prudent and necessary step.

Understanding and implementing quality cable management solutions like cable tray insert plastic not only protects your investment in infrastructure but also ensures operational efficiency and safety. Whether upgrading an existing setup or designing a new installation, consider the protective benefits and reliability enhancements that these inserts offer.
