CONCEALED KNOB FOR FLUSH DOORS

The concealed knob of Invisibledoor doors is an ideal solution for a perfectly invisible rendering. The push/pull system allows you to close the flush-fitting doors with a slight hand pressure. The knob fits into the leaf of the door, and is perfectly embedded when closed. The doors are also equipped with retractable adjustable hinges and a frame that can blend in with both masonry and plasterboard walls.
