Recessed junction box ELEKTROPLAST 0260-0N for plasterboard 89×89×50mm fire-retardant

ELEKTROPLAST 0260-0N recessed junction box for plasterboard 89×89×50mm is a purpose-built enclosure for flush mounting electrical fittings and wiring within drywall constructions. The box is formed from a self‑extinguishing thermoplastic material to reduce fire propagation and features multiple cable entry points and mounting options compatible with common electrical fixtures in residential and light commercial interiors.

Advantages

The junction box offers a compact footprint suitable for standard plasterboard thicknesses while maintaining a 50 mm internal depth to accommodate terminals, connectors and wire splices. Its self‑extinguishing material improves fire safety compared with non‑treated alternatives. The design includes multiple knockouts and entry points for flexible cable routing and secure fixation to drywall frames or mounting brackets, simplifying installation and future maintenance.

Suitable for

• Flush mounting light switches, sockets and control devices in plasterboard/drywall partitions
• Housing wire splices and terminal blocks in residential and light commercial interiors
• Installations requiring a compact, fire‑retardant enclosure with multiple cable entry options

When it may not be suitable

This recessed junction box is intended for use in plasterboard (drywall) systems and may not be appropriate for solid masonry or concrete installations without compatible adapters or additional mounting hardware. It is not designed to provide ingress protection against water or dust in exposed or outdoor environments; for such locations, specialized sealed enclosures are recommended.

Key specifications

• External dimensions: 89 × 89 × 50 mm (width × height × depth)
• Material: self‑extinguishing thermoplastic
• Mounting type: recessed (flush) for plasterboard walls
• Cable entry: multiple knockouts/entry points suitable for standard electrical cables
• Internal depth: 50 mm to accommodate connectors and splices

How to use

Cut an opening in the plasterboard matching the box footprint and depth, align the recessed junction box within the cavity, and secure it to the drywall framing or with compatible mounting brackets as required. Route incoming cables through the provided entry points, make electrical connections following local wiring regulations, and close the box with the appropriate cover plate or fixture. Ensure all connections are insulated and supported, and verify the mounted device sits flush with the finished wall surface.

What to consider before purchase

• Verify the plasterboard thickness and cavity depth to ensure proper flush mounting
• Confirm the internal depth and volume are sufficient for planned connectors, terminals, and wire splices
• Check compatibility with the specific switches, sockets or fixtures to be installed
• Ensure the product material and fire‑retardant properties meet any applicable local regulations

Usage recommendations

For safe and compliant installation, follow local electrical codes, secure cables with appropriate clamps or grommets at entry points, and avoid overcrowding the box with too many conductors or bulky connectors. Use proper cover plates sized for 89×89 mm mounting or compatible fixture frames to maintain a neat finish and preserve the fire‑retardant integrity of the installation.
