Vimar 8-Module Rectangular Flush Mounting Box, For Masonry Walls, Glow Wire 650°C, Halogen-Free Plastic, 20/25 mm Conduit Knockouts, Light Blue

Overview

The Vimar VMV71318 is an 8-module flush mounting box for masonry walls, sized at 145.00 mm x 124.50 mm with an inner depth of 50.00 mm and an installation depth that can be set up to 56.80 mm. It gives you a clean in-wall base for mounting 8-module device supports and keeping terminations and cable routing organized behind the finished faceplate.

The light blue body makes it easy to spot during rough-in, and the box is built around typical conduit-style installations with break-out entries for 20 mm and 25 mm runs. For marine projects, it fits best in protected, building-style spaces such as marina facilities, dock utility rooms, or interior refit areas where wiring is routed in conduit inside solid walls.

Key features

• 8-module rectangular flush mounting box intended for masonry walls
• Overall size 145.00 mm (L) x 124.50 mm (W) with 50.00 mm inner depth
• Depth range up to 56.80 mm to suit different wall builds and finish thickness
• Glow Wire 650°C rating for higher heat resistance in the wall cavity
• Break-out openings for 20 mm and 25 mm conduit, with rear cable entry support
• Couplable format supports multi-box banks when using compatible coupling joints
• Zinc-plated fixing lugs help keep threads clear so device supports screw in cleanly after plastering
• Accessory-ready layout supports items such as anti-mortar covers and a rack for a dividing screen

Compatibility and fit

This box is built around an 8-module layout, so confirm the device support and front frame you are installing are the matching 8-module format. Before cutting in, check the available cavity depth and finishing layers so the box can sit flush and still leave working room for conductors behind the device.

For conduit runs, plan entries around 20 mm or 25 mm pipe sizes and use the break-out points that keep bends gentle and cable pulls clean. If you are coupling multiple boxes, keep alignment tight at the rough-in stage so the finished frames sit straight across the whole bank.

Installation and setup

Set the box into the masonry opening so the front edge lands flush with the intended finished surface. Pop the required knockouts, route conduits, and leave enough slack for terminations and device removal later. During plastering and finishing, keeping the box protected helps prevent debris from building up where the device support needs to seat and screw down.

Once the wall is finished, mount the device support by screwing it into the fixing lugs, then complete terminations and fit the faceplate. If you are dividing circuits inside the box, a separating screen can be fitted where your installation calls for it.

Use cases on board

This is a practical match for electricians and boatyard teams building out shore-side electrical areas or interior refit spaces that use in-wall conduit and modular switching. For exterior marine locations exposed to spray or washdowns, use an enclosure that carries an appropriate IP rating for the environment.

Many products sold by Apollo Lighting include a manufacturer's warranty covering defects in materials or workmanship. Warranty terms vary by brand, product category, and model, so eligibility, coverage duration, exclusions, and available remedies are determined by the applicable manufacturer. We recommend reviewing the warranty information provided with your product before installation or use, especially for marine electronics, navigation equipment, lighting, electrical systems, pumps, safety equipment, and other specialized marine products.

If you need warranty service, the claim must follow the process established by the manufacturer, authorized service center, or designated warranty provider. You may be asked for proof of purchase, a serial number, product registration, photos, maintenance or installation records, or other documentation. Apollo Lighting does not determine or modify a manufacturer's warranty coverage or final claim decision, but we are happy to help provide purchase information and direct you to the appropriate manufacturer or warranty resource.

Keep your receipt, product documentation, serial number information, and original packaging when practical. Damage caused by normal wear, misuse, improper installation, insufficient maintenance, corrosion, impact, unauthorized modifications, electrical issues, or operation outside the manufacturer's specifications may not be covered. Warranty claims are separate from standard returns, so a product that has been installed, used, or exposed to marine conditions may no longer qualify for return while still remaining eligible for evaluation under the manufacturer's applicable warranty.
