Our Heritage Black Clear Glazed (without lock-block) Internal Doors are supplied with a symmetrical look, and without a traditional lock block. These doors give those Interior Designers looking for a minimalist look the perfect solution. Supplied with Clear Toughened Glass as standard, and narrow 70mm door stiles, and 90mm rails. These doors are ideal for creating side-panels or static room dividers too! Finished in a high quality Smooth Black primed paint finish, these doors are ready for that final coat. Please note that these doors, with no lock block require a narrow backset latch to fit into the door stile. Alternatively, a magnetic latch can be used. They are not suitable for traditional 65/75mm backsets.
