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.

Connecting HDPE Pieces

There are two ways to connect multiple pieces of HDPE together. One method is to overlap the HDPE and use our double sided seam tape to connect the two pieces. The other method is to butt the ends together and use our 17 mil single sided seam tape to create a solid connection.

Overlap Method
(for underground installations)

The overlap method is best used when connecting two pieces of HDPE in a buried application. Due to the overlap, a ridge is exposed which is not ideal when installed in exposed vertical or flat installations in high traffic areas as there is a possibility of an object catching on the ridge and pulling the two pieces apart.

In a below ground installation, the large overlap area provides a more water resistant connection as well as enhanced protection against tree and plant root intrusion.

End to End Method
(for exposed installations)

When installing HDPE on a wall, floor or anywhere that is exposed, the end to end method provides a secure connection and does not leave any ridges exposed to potential catching by a person or object.

HDPE Cable Tray Insert Liner

Cable Tray Insert Liners for Smooth Cable Routing

Cable tray systems are widely used to organize and support wiring throughout commercial, industrial, and infrastructure projects. While open cable trays make wiring accessible, the tray structure itself can create openings, cross members, seams, and other contact points beneath the cables. Installing a cable tray insert liner creates a smooth, continuous surface that can make routing, positioning, and managing cables easier.

What Is a Cable Tray Insert Liner?

A cable tray insert liner is a flexible sheet material placed along the bottom of a cable tray to create a solid surface beneath the wiring. Longview Supply cable tray insert liners are manufactured from high density polyethylene, commonly referred to as HDPE.

The smooth plastic surface provides separation between cables and the open structure of the cable tray. This can be especially helpful when cables are being pulled through long tray runs or when smaller wires are being installed in trays with relatively large openings.

Because the material is supplied in flexible rolls, it can be cut and fitted to accommodate a variety of cable tray layouts and dimensions.

Creating a Smooth Surface for Cables

One of the primary benefits of a cable tray insert liner is the smooth surface it creates beneath cables. Without a liner, cables may come into direct contact with cross wires, seams, openings, or other structural features of the tray. These contact points can make pulling and positioning cables more difficult.

An HDPE liner provides a continuous surface across the bottom of the tray, helping cables move more easily during installation and providing a consistent surface for them to rest on once installed.

The liner can also help prevent smaller wires and cables from dropping through larger openings in wire basket and other open-style cable trays.

Flexible HDPE Material

HDPE provides a useful combination of flexibility and durability for cable tray lining applications. Unlike rigid panels, roll-form HDPE can follow many common tray configurations and can be adjusted directly at the jobsite.

The material can be cut with a utility knife or other appropriate cutting tool, making it easy to trim around bends, fittings, supports, junctions, openings, and other tray features.

Longview Supply cable tray insert liners are available in both 30 mil and 40 mil thicknesses. Multiple widths ranging from 18 inches to 48 inches are available for different cable tray sizes, and standard rolls are 100 feet long.

Planning a Cable Tray Liner Installation

Before installing a cable tray insert liner, determine the inside width of the cable tray and identify any bends, transitions, supports, fittings, or other areas where the liner may need to be trimmed.

The material should be positioned along the bottom of the tray to create a smooth cable-bearing surface without interfering with the intended operation of the cable tray system.

For longer installations, multiple pieces of HDPE may be required. Sections can be cut and fitted according to the requirements of the installation. When joining pieces is necessary, the appropriate connection method should be selected based on the tray configuration and project requirements.

Common Cable Tray Insert Liner Applications

Cable tray insert liners may be used in a variety of commercial and industrial cable-management applications where a smooth, solid surface is desired inside an open cable tray.

Typical applications may include manufacturing facilities, warehouses, equipment rooms, utility installations, telecommunications facilities, commercial buildings, and other locations where cables are routed using wire basket or open-style cable tray systems.

Choosing the Right Cable Tray Insert Liner

Selecting the appropriate liner begins with measuring the cable tray and determining the width and thickness required for the project.

Longview Supply offers several roll widths along with both 30 mil and 40 mil HDPE options, allowing the material to be used with a variety of cable tray dimensions. The flexible roll format also makes the liner practical for long cable runs and installations that require field trimming.
