Our cable 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.

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 Liner

Cable Tray Liners for Smooth Cable Routing

Cable tray systems provide a practical way to route and support electrical, communication, and other cabling throughout commercial and industrial facilities. Depending on the tray style, the open bottom, seams, cross wires, and other features may create areas where cables can catch during installation. Installing a smooth plastic liner along the bottom of the tray creates a more continuous surface for cables to rest on and pass across.

What Is a Cable Tray Liner?

A cable tray liner is a sheet of material installed inside a cable tray to create a solid surface beneath the cables. Longview Supply cable tray liner is manufactured from high density polyethylene, or HDPE. The material combines a smooth surface with enough flexibility to conform to many common tray configurations.

Because the HDPE is supplied in rolls, it can be cut in the field to accommodate different tray widths, bends, openings, transitions, and other installation details. This makes the liner useful for both new cable tray installations and existing trays where a solid bottom surface is desired.

Benefits of Using HDPE in Cable Trays

One of the primary benefits of an HDPE cable tray liner is its smooth surface. When cables are pulled or positioned through an open wire tray, wires or cable jackets can encounter cross members, openings, or other irregularities. A liner creates a continuous layer between the cabling and the tray surface, helping reduce snagging and direct contact with these features.

The liner can also help contain smaller wires or cables that might otherwise pass through larger openings in an open-style tray. For installations that may require future cable additions or changes, a smooth tray bottom can make repositioning and routing cables easier.

Flexible Material for Field Installation

HDPE is flexible enough to follow many typical cable tray layouts while remaining durable for use as a liner. The material can be cut with a utility knife or other appropriate cutting tool, allowing installers to make adjustments at the jobsite.

Longview Supply offers cable tray liner in 30 mil and 40 mil thicknesses and in multiple roll widths for different tray sizes. Standard rolls are 100 feet long, making it possible to cover extended tray runs with fewer individual sections.

Planning a Cable Tray Liner Installation

Before installation, measure the inside dimensions of the cable tray and identify bends, fittings, supports, junctions, and other areas that may require the liner to be trimmed. The material should be positioned so it creates a smooth surface without interfering with the intended function of the cable tray or other system components.

Where multiple pieces are required, the sections can be cut and fitted according to the needs of the installation. The appropriate method of securing or joining the material will depend on the tray design and project requirements.

Common Cable Tray Liner Applications

HDPE cable tray liners may be used in commercial and industrial cable-management applications where a smooth, solid tray surface is desired. Examples include manufacturing facilities, warehouses, utility areas, equipment rooms, commercial buildings, and other locations that use open or wire-style cable trays.

IMPORTANT APPLICATION INFORMATION

This product is general-purpose HDPE sheet material. It is not represented or certified as flame-retardant, fire-rated, plenum-rated, low-smoke, or UL 94 V-0. Requirements for cable tray liners vary by installation and project. The purchaser, system designer, and installer are responsible for determining product suitability and compliance with applicable codes, project specifications, cable tray manufacturer requirements, conductor ampacity requirements, and requirements of the authority having jurisdiction.
