Product Specifications

Trinity Range Integration

The Trinity Blank Cover 4X4 is meticulously designed to be visually indistinguishable from the frame of any other Trinity 4x4 device, such as the 4-lever or 6-lever switches. When installed, it blends in perfectly with adjacent Trinity products, ensuring absolute continuity of the sleek, modern design language.

Ideal Use

A 4x4 blank cover is used in any situation where a 4x4 wall box is installed but is not currently required for an active device.

• Decommissioned Multi-Gang Switches: The perfect way to safely and neatly cover a 4x4 switch point that is no longer in use.
• Large Junction Boxes: Used to provide a safe, secure, and aesthetically pleasing cover for major junction boxes within a wall.
• Future-Proofing New Builds: Ideal for covering pre-installed 4x4 wall boxes in strategic locations (like entertainment areas or kitchens), allowing for future installation of a complex control panel or socket outlet.
• Removing Old, Large Devices: Use to cover up holes left from old, removed technology like large, outdated alarm keypads, intercom stations, or old thermostat controls.
• Maintaining Wall Symmetry: Can be installed for purely aesthetic reasons to balance a wall where a functional 4x4 switch on one side needs a matching visual element on the other.

Tips

• Ensure Internal Wiring is Safe: Before installing the blank cover, it is a critical safety step to ensure any wires within the box are correctly and safely terminated. A qualified electrician must perform this, typically using approved connectors and insulation.
• Level Mounting is Crucial: A 4x4 plate is large, and any misalignment will be very noticeable. Always use a spirit level during installation to ensure the cover is mounted perfectly straight for a professional finish.
• Do Not Over-tighten Screws: Tighten the four mounting screws until the plate is snug and secure against the wall. Over-tightening can put stress on the polycarbonate frame and potentially cause it to crack.
• Cleaning and Care: To clean the cover plate, use a soft, dry, or slightly damp cloth. Avoid using abrasive cleaners, scouring pads, or chemical solvents, as they can permanently damage the smooth finish.
• Junction Box Accessibility: Remember that according to wiring regulations, a junction box must always remain accessible. Do not install this cover and then permanently obstruct it with fixed cabinetry or wall features.
