Wall-Smart 085-1NA17-UBL Flush In-Wall Adapter Sonos ARC / Magnetic Grille / Paintable / UK US Backbox

Description

The WS NC for Sonos ARC US/UK is a flush in-wall adapter designed to conceal a Sonos ARC sound bar while preserving full access and operation. It provides a clean, built-in appearance that sits flush with the wall and integrates with standard drywall finishes. The adapter is supplied unpainted so it can be finished to match the surrounding wall.

Key features include a magnetic acoustic grille, paintable surface, and knockouts for UK or US backboxes and sockets. The grille is offered in white or black acoustic cloth and is IR transparent to maintain remote control functionality. The adapter supports straightforward insertion and removal of the sound bar for service or adjustment.

Technically the adapter is engineered for high fidelity audio output and is sized to accommodate the Sonos ARC sound bar while preserving acoustic performance. It is constructed from moisture resistant MDF that complies with TSCA Title VI standards. The product dimensions are 1516.4mm / 297.2mm / 158.6mm and the weight is 6.7Kg.

Connectivity and compatibility are simplified by built-in knockouts for UK BS4662 2 Gang backboxes or equivalent and US HUBBELL Racobox 420 or equivalent. An alternative EU/IL backbox option is available under model numbers 085-1NA17-EBL and 085-1NA17-EWH. The grille cloth options are listed as UWH for white and UBL for black.

Practical applications include concealed residential home theaters, minimalist living rooms where the soundbar is hidden behind the wall, and commercial spaces requiring recessed audio aesthetics. The magnetic grille supports quick access for maintenance while preserving the installed look. The adapter is intended for use with the Sonos ARC sound bar which is not included.

Installation follows standard drywall construction procedures and is designed for 1/2 in drywall. The unit ships unassembled and should be painted after installation to blend with the wall finish. For complete installation instructions refer to Wall-Smart installation instruction.
