TF Series — Trimless · Flush · Floor Box
Trimless Floor Box –
Invisible in Your Floor

Three Installation Methods
Pick how visible you want the floor box to be. From completely concealed under your finish, to a clean stainless flush, to a minimal flush frame.
Fully Hidden
Lid is covered with the same flooring material — marble, tile, wood or carpet — so the floor box is completely invisible until opened.
Frame Flush
Only a thin frame is visible, level with the floor. Quick to specify and works with almost any floor finish.
SS Panel Flush
A stainless steel lid sits perfectly level with the floor surface — flush, clean, and built to last. The brushed SS304 finish resists scratches, corrosion, and heavy foot traffic, making it the preferred choice for high-use commercial spaces such as offices, hotels, and public halls.
Compatible With Any Floor Finish
The TF Series accepts the same finish as the surrounding floor — so the box truly disappears.
Marble
Drop in a matching marble tile — luxury hotels and showrooms.
Tile
Ceramic or porcelain tile insert — seamless with any tiled floor.
Wood
Hardwood or engineered timber insert — perfect for residential and office.
Carpet
Carpet tile insert — invisible in open-plan corporate floors.
