Catalog Numbering System
The following information will help you order straight sections for your application. Refer to Table1 in Fiberglass Technical Data section for Working Allowable Load Capacity. All cable trays are available in polyester and vinyl ester resin. See page 8 to determine resin system required. Cable trays requiring a 2.0 safety factor will be designated with a "D" prefix. See page 6, Table 1.

Combine all four specification numbers to create the correct catalog number..

Notes:
Cable tray is available with a strut rung upon request, please see page 31.

STRAIGHT SECTION COVERS

Cable tray covers are recommended for those areas where the cable needs protection from falling objects, adverse weather conditions, etc. Available in polyester and vinyl ester resin types in 10 Ft. (3m) sections in both flat and peaked design. When ordering flat cover for fittings, refer to pages 18 and 21. If vinyl ester is requested, substitute "V" for "P" as in the following example: EVC-06x10'. In addition to cover, solid bottom also available. See page 26 for cover accessories.

SPLICE PLATES & FASTENERS

Enduro offers a full line of fiberglass splice plates designed to provide a structural transition between straight sections and fittings.

It is important to refer to NEMA FG-1 regarding proper tray installation as it pertains to support and splice plate locations for straight sections and fittings. Refer to page 10 for recommended support locations.

Splice plates and fasteners are sold separately and are not provided as standard with straight sections or fittings due to the many hardware options. All plates have 7/16" pre-drilled bolt holes.

The catalog numbers contained herein are for Polyester Resin connector plates. For Vinyl Ester connector plates, insert the letter "V" as indicated in this example.
Example: ESP-6C-180 Polyester ESP-6V-180 Vinyl Ester

Expansion plates have 1" slotted holes allowing 5/8" total contraction and expansion. Refer to Table 5 on page 8, Thermal Contraction and Expansion, for maximum spacing between expansion joints.
