Inspection wall box CALEFFI 360050 — plastic, 500×250×90 mm

Inspection wall box CALEFFI 360050 is a plastic access panel with external dimensions 500×250×90 mm, designed to be installed in walls or panels to conceal and protect valves, fittings and small service components while allowing easy access for maintenance and inspection. The compact rectangular body provides a flush and unobtrusive finish for plumbing, heating and utility installations where serviceable yet concealed connections are required.

Advantages

The CALEFFI inspection box is made from durable plastic that resists dust and light mechanical impacts, helping to protect internal components and prolong their service life. Its standardized dimensions simplify installation into common wall cavities and panel openings. The unit allows straightforward access for servicing without the need to remove large wall sections, reducing repair time and potential damage to finished surfaces.

Suitable for

• Plumbing installations where shut-off valves or fittings need to be concealed but remain serviceable
• Heating systems with concealed connections or small control components
• Utility rooms and technical panels requiring protected, accessible junction points

Key specifications

• Material: plastic
• External dimensions: 500 × 250 × 90 mm
• Mounting type: wall/panel-mounted access box
• Purpose: housing valves, fittings and small service components
• Protection: reduces dust entry and shields against minor mechanical damage

How to use

Cut an opening in the wall or panel matching the external dimensions of the inspection box and insert the unit so its front face is flush with the finished surface. Secure the box according to the substrate and local installation practices, then route pipes, fittings or small components into the cavity before closing any surrounding finishes. Use the access panel to reach internal valves and fittings for routine inspection, adjustment or repair without dismantling the wall.

Usage recommendations

Install the box in a location that allows comfortable access to internal components and avoids obstruction by furniture or fixtures. Verify compatibility of the internal components’ sizes with the box cavity before installation. Clean the area and remove debris before mounting to ensure a stable fit; avoid exposing the plastic housing to high-temperature sources or open flames.
