The Crystal Knob is experiencing something of a renaissance in interior design and many door furniture companies are releasing new designs. The Gainsborough Sonata Crystal Knob is fine example of a crystal knob and is extremely eye-catching. A strong look and feel, this knob would sit beautifully in both contemporary and older-style designs.

Available As Passage Set

The Sonata Knob comes as a mortice set and is finished in either bright gold or bright chrome. It has a latchset with knobs or levers on both sides of a door. It would suit bedroom, dining room and lounge doors in a variety of settings.

Combine With Privacy Adaptor

If you want to use the Crystal Knob as a locking facility it is very simple to add a Gainsborough privacy adaptor to lock bathroom, bedroom and office doors. The privacy adaptor has an inside locking snib and emergency release from outside. It fits snugly behind the backplate of the knob. This is especially useful for children and elderly people who may need assistance in getting out of a room if they have an accident inside and need to be rescued.
