Frequently Asked Questions
- What is a dummy knob and when should it be used?
A dummy knob is a non-operating decorative door knob that does not turn or operate a latch mechanism. It is used on inactive door panels, the non-operating side of double doors, or purely decorative applications where the appearance of a knob is desired without functionality. - Can this dummy knob be used with active Symmetry locksets?
Yes. The Symmetry dummy knob is designed to coordinate aesthetically with active Symmetry locksets, providing matching appearance across operating and non-operating doors within the same property. - Does the dummy knob require the same door preparation as operating locksets?
No. Dummy knobs typically require only a simple through-hole for the mounting screw and do not require latch preparation, backset drilling, or strike plate installation that operating locksets need. - What is the OneCyl system and does it apply to dummy knobs?
OneCyl is Lockwood's exclusive cylinder assembly solution that allows cylinder interchangeability in operating locksets. While dummy knobs do not contain operating cylinders, they are part of the Symmetry range that features OneCyl compatibility in its active lockset models. - What door thickness range does this dummy knob accommodate?
The Symmetry dummy knob is suitable for timber doors with thickness ranging from 32mm to 46mm, covering most standard residential door applications.
