AVE 25ESP3L coupler expander: more space and more order in installation
The long side coupler expander AVE 25ESP3L is the accessory designed to simplify and clean up installations on 2503MG masonry boxes. In many modern systems, box space can become a limitation: more numerous cabling, connectors, home automation modules, or TV branches require larger volumes and more rational cable passage. This component addresses both needs, offering a flexible solution: it can work as a coupler to connect two boxes or as an expander to increase capacity on the long side.
Coupler function: connects two boxes and creates a dedicated cable passage
Used as a coupler, the 25ESP3L allows two 2503MG boxes to be coupled via the long side, maintaining a constant and orderly distance between the seats. This is particularly useful when creating adjacent control points (e.g., multiple devices, command/socket/data combinations) or when preparing a modular system. Additionally, the accessory facilitates the passage of cables from one box to another, avoiding improvised solutions and reducing the risk of pinching or too tight bends that can compromise cable order.
Expander function: more volume for home automation and bulky accessories
When internal space becomes critical, the 25ESP3L can be used as an expander, enlarging the long side of the box. This possibility is valuable for housing components that require more depth or volume, such as home automation spiders, interface modules, bulkier junctions, TV splitters, or devices that need better cable management. The advantage is twofold: a cleaner installation is achieved, and room is left for future integrations without having to intervene again on the masonry.
Why it's worthwhile: professional installation and future-ready system
In a well-designed system, accessories like this make a difference: they improve the arrangement of components, increase practicality for the installer, and reduce time and complications during connection. Moreover, providing adequate space and cable passages makes the system more future-proof, ready for home automation expansions or multimedia additions.
