Overview

The Vimar VMV71571 is a multifunction accessory for 2-module hollow wall boxes that helps you center the cutout, support the box from the inside of the panel, and link multiple boxes into a clean horizontal or vertical bank. It is a compact part at about 9 x 8 x 0.3 cm and it weighs about 0.00518 kg, so it sits flat behind thin liners and furniture panels without taking up useful depth.

On a boat, this is the small piece that keeps a switch or outlet location from looking slightly off when the panel has flex, vibration, or a tight working angle. It is also useful when you are laying out more than one 2-module position and you want the spacing to stay consistent so the finished devices and cover plates line up.

Key features

• Made for Vimar 2-module hollow wall box installations, acting as a frame on the inside of the panel
• Built-in centering template function to help mark and align the opening before you commit to the cut
• Coupling joint function for assembling horizontal or vertical banks of 2-module boxes
• Low-profile footprint of about 9 x 8 x 0.3 cm for use behind tight cabin liners and joinery panels
• Lightweight part at about 0.00518 kg, adding support without adding bulk behind the mounting surface
• Useful when the mounting surface is a thin bulkhead, liner, or cabinet panel where keeping alignment is the hardest part

Installation and setup

Dry-fit the box position behind the panel first, then use the centering template function to lay out the cutout so the device opening lands square and level. After the opening is prepared, the accessory works from the inside of the panel as a support frame for the 2-module box.

When you are creating a switch bank, assemble the boxes as a horizontal or vertical group before pulling final wiring, so the spacing stays consistent and the finished face sits straight. Leave enough service slack so the devices can be removed later without stressing the conductors inside the wall cavity.

Compatibility and fit

This accessory is for Vimar 2-module hollow wall boxes and is commonly paired with round hollow wall box formats such as V71701. Confirm that your installation box is the 2-module hollow wall style and that you have adequate clearance behind the panel for the box depth, wiring bend radius, and any connectors.

It is best suited to interior panels and protected locations where hollow wall boxes are used, such as cabin liners, joinery panels, head compartments, and enclosed console areas.

Use on board

This is a good match for refits where you are adding new switching points and want them to look straight even on curved or slightly flexible surfaces, and for new builds where you are grouping controls in a tight space at the helm or nav station. It is also helpful when you need multiple 2-module positions to align cleanly across a bulkhead or cabinet face.
