FIBERGLASS ENCLOSURE BODIES
Fiberglass Enclosures for Metering and Distribution
Select the body around the equipment and installation. FN supplies molded fiberglass enclosure bodies for distribution, cable-branch and metering applications. Dimensions, doors, compartments and mounting interfaces are selected by model.
Choose the body layout to suit the equipment and required access.
SMC or DMC compound is identified for the selected model.
Check the overall envelope and usable internal space together.
Meter-box forms use application-specific viewing and compartment arrangements.
Use the selected drawing to define the hole pattern, support and entry locations.
Electrical devices, wiring and assembly are separate quotation items.
Best fit
- Distribution and cable-branch projects needing a housing for specified internal equipment.
- Metering projects with a defined viewing-window and access arrangement.
- OEM projects sourcing the enclosure body separately from the electrical components.

Example distribution-body dimensions
Each example below lists overall body dimensions (H × W × D), followed by the installation dimensions shown. Availability and supplied parts are set out in the selected model drawing and quotation.
| Overall size — H × W × D | Installation dimensions shown |
|---|---|
| 300 × 250 × 150 mm | 240 × 165 mm |
| 400 × 300 × 180 mm | 335 × 222 mm |
| 500 × 400 × 200 mm | 438 × 322 mm |
Installation dimensions are separate from body size. Check actual hole centers and the supporting structure against the selected model drawing. The examples above do not define a continuous size range.
Meter-box layouts
Meter-box bodies use application-specific viewing windows and access arrangements. Specify the meter type, number of positions, compartment layout and required clearance when choosing the body.
Requested changes
Send a marked-up drawing for additional openings or a different interface. Non-standard dimensions, window changes and cut-outs require a feasibility review for the chosen model and molding method. Accepted changes are recorded in the drawing and quotation.
