Wire Tray Liner


SKU LV-18-30-100

Our Wire Tray Liner 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.

Optimizing Cable Management: The Advantages of Wire Tray Liners

Effective cable management is a cornerstone of modern electrical and data installations, ensuring that systems are not only efficient but also safe and easy to maintain. Wire tray systems are widely used due to their flexibility and ease of access, but they can be significantly enhanced with the use of wire tray liners. This blog post explores the benefits of wire tray liners, their applications, and why they are essential for optimizing your cable management solutions.

What are Wire Tray Liners?

Wire tray liners are protective layers designed to be placed inside wire cable trays. These liners are usually made from durable materials like polyethylene, PVC, or rubber, each chosen for specific properties such as durability, flexibility, and resistance to environmental factors. The primary role of wire tray liners is to provide a smooth, protective surface that shields cables from potential damage caused by the metal structure of the wire trays.

Key Features:

Protection: Guards against physical damage from sharp edges and rough surfaces.
Durability: Resistant to chemicals, oils, and extreme temperatures.
Flexibility: Easily customizable to fit various shapes and sizes of wire trays.
Electrical Safety: Enhances the overall safety by providing additional insulation.

Benefits of Using Wire Tray Liners

Incorporating wire tray liners into your cable management system offers several significant advantages:

Improved Cable Protection

Wire trays, while excellent for cable management, often have open designs that can expose cables to environmental hazards and mechanical damage. Wire tray liners act as a buffer, protecting cables from abrasion and entanglement, thus extending their lifespan and reducing the risk of cable failure.

Enhanced Safety

The additional layer of insulation provided by wire tray liners can be crucial in preventing electrical hazards, particularly in environments where there is a high risk of moisture or chemical exposure. This added safety measure helps in minimizing the risk of short circuits and electrical fires.

Ease of Maintenance

Wire tray liners simplify maintenance routines by providing a smooth surface that is easy to clean and inspect. This feature is particularly beneficial in environments where cleanliness and hygiene are priorities, such as in food processing plants or hospitals.

Aesthetic Considerations

Apart from functional benefits, wire tray liners can improve the visual neatness of cable management systems. They help in hiding cables from view and providing a more organized appearance, which is especially important in areas where infrastructure is visible to the public or in professional settings.

Applications of Wire Tray Liners

The versatility of wire tray liners makes them suitable for various settings, including:

Commercial Buildings: Enhances safety and aesthetics in areas where cables must be both accessible and discreet.
Industrial Facilities: Offers robust protection against the harsh conditions typical of manufacturing environments.
Data Centers: Crucial for protecting sensitive data cables from physical and environmental damage.
Healthcare Facilities: Ensures a high level of safety and cleanliness, critical in medical environments.


Wire tray liners are an invaluable addition to any cable management system, providing essential protection, enhanced safety, and improved aesthetics. By incorporating these liners into wire tray systems, businesses can achieve more reliable and safer installations, which in turn can lead to greater operational efficiency and reduced maintenance costs.

Whether upgrading an existing system or designing a new installation, considering the integration of wire tray liners is a wise investment that can lead to significant long-term benefits. Recognizing the critical role these liners play in protecting and optimizing cable systems is key to maintaining high standards in cable management.
