Akuvox E21-IWB In-Wall Flush Mount Box for E21A/E21V Intercoms

Akuvox E21-IWB In-Wall Mounting Box

The Akuvox E21-IWB is a purpose-built flush-mount installation box designed to house the Akuvox E21A audio intercom and E21V audio-video intercom within a masonry or plaster wall. Rather than sitting on the wall surface, the intercom is recessed into this steel back box, giving door stations a clean, streamlined, professional finish that sits flush with the surrounding wall. It is the recommended flush-mount accessory for sites where a discreet, tamper-resistant installation is preferred over a surface-mounted housing.

Key Features

• Flush/in-wall design that recesses the E21 series intercom neatly into masonry or plasterboard walls
• Durable steel construction built to support the weight and vandal-resistant housing of the E21 series
• Purpose-matched fit for the Akuvox E21A (audio-only) and E21V (audio and video) door intercoms
• Simplifies cable management by providing a concealed cavity for PoE/network cabling behind the intercom
• Complements the vandal-resistant aluminium body of the E21 series for added structural support
• Straightforward installation using standard mounting hardware and wall-chase techniques
• Ideal for new-build or renovation projects where conduit and cabling can be run inside the wall cavity
• Consistent aesthetic across entrances, lobbies, and gated access points using the same E21 intercom family

Typical Applications

The E21-IWB is best suited to commercial, industrial, and multi-residential entrances where an Akuvox E21A or E21V intercom is being installed into a solid or stud wall and a low-profile, flush finish is desired. It is commonly specified for apartment building entries, gated communities, school and hospital entrances, and secure perimeter doors, where installers want the robustness of the E21 series intercom combined with a neat, recessed appearance rather than an exposed surface-mount housing.

Frequently Asked Questions

Is the E21-IWB compatible with both the E21A and E21V?Yes, this in-wall box is designed to suit both the Akuvox E21A audio intercom and the E21V audio-video intercom, as they share the same body dimensions.

Do I need the E21-IWB if I already have an E21 intercom?The E21 intercom units are sold separately from their mounting boxes, so the E21-IWB (or the surface-mount alternative) needs to be purchased separately for a complete flush-mount installation.

Can this box be used outdoors?The E21-IWB is intended for flush mounting into an external or internal wall; once the intercom is fitted, the combined assembly relies on the intercom's own IP-rated housing for weather resistance.
