The Coswall internal mounting box is a specialized component designed to provide a recessed housing for light switches and electrical sockets. Specifically sized at 144mm by 67.5mm, this back cassette is engineered to accommodate larger switch plates, particularly those measuring 154mm by 72mm. For homeowners or renovators moving away from standard square or round fittings, this box is a necessary foundational piece that ensures your electrical hardware sits flush and secure against the wall surface. While it is a utility item that remains hidden after installation, its precision is critical for the aesthetic success of your electrical upgrades.
Marketed under the Coswall brand, which has a significant presence in the international electrical hardware space, this mounting box addresses a common pain point: finding compatible housings for non-standard or oversized decorative plates. With a buyer rating that leans toward the top of the scale, initial feedback suggests that the product meets the physical expectations of its users. However, since it is an internal component, the success of the installation depends entirely on the accuracy of your wall cut and the specific compatibilit

Who it's for: This is primarily for DIY enthusiasts and professional installers who have already selected 154mm x 72mm switch plates and need a matching internal cassette. It is ideal for those performing new installations or significant wall renovations where internal mounting is possible.
Who should skip it: This product is not suitable for users with standard pre-existing wall boxes who are looking for a simple 'swap-in' solution without modifying their walls. It is also incompatible with standard single-gang or round electrical fittings.
🔎 Check before you buy
- Confirm the exact depth of the box with the seller to ensure it fits your wall thickness.
- Ask the seller about the material composition and if it carries any specific fire-retardancy ratings.
- Verify the spacing between the screw mounting holes to ensure they align perfectly with your specific switch plate.
- Clarify if the box includes knockouts for standard conduit sizes used in your region.
💡 Tips

- Consider purchasing a few extra units beyond your current needs to account for installation errors or future repairs, as these specific sizes can go out of stoc
- Check if your switch plate comes with its own screws, as mounting boxes sometimes require specific thread types.
