Antique Furniture Locks for doors - drawers

	Antique Furniture Locks:
	Replacing old locks on antique furniture can be challenging as many sizes of old locks are not in production today. This can make finding an exact match difficult and sometimes not possible. The most important measurement when replacing an existing lock is the backset. Backset is the distance between the selvedge edge and center of pin in the keyhole. It is the most crucial measurement when replacing missing locks.........the key when inserted through your keyhole must line up with the pin in the center of the lock keyhole. If the backset measurement does not match it will be necessary to alter the keyhole in the door or drawer of the piece of furniture. Antique style locks are available in 3 basic styles: surface, half mortise and full mortise. Keyhole covers and escutcheons provide a protective and finished edge to the keyhole. Styles range from simple insert escutcheons, classic round covers to larger decorative plates in polished and antique finishes Key Blanks and Lock Strikes Skeleton keys and key blanks can be used on some antique locks. Key blanks have a plain tab which can be cut to operate many locks. Skeleton keys have the tab already cut and will work some locks.

3 distinct types for furniture and cabinets: surface, half mortise and full mortise

Specific Lock Terminology

Surface Locks
Surface Locks are used on furniture and cabinet doors, no mortising is required as lock mounts directly
to the inside of the cabinet door. A strike is rarely used as the bolt ejects behind the adjacent door stile or frame. These locks are normally reversible meaning they will work both right and left hand doors.

Full Mortise Locks
Full Mortise Locks are used on drawers, doors and desks. These locks require a deep mortise when installing. They provide a minimalist appearance
as only the selvedge is seen.

Half Mortise Locks
are used on drawers, doors, desks and boxes. They are available in two styles: 1. for drawers, doors and desks and 2. for boxes with lift lids. They require some mortising to install.

1. Locks for drawers, doors, and desks this very common style was frequently used on 18th & 19th century antique furniture. These locks were designed with the keyhole off-center. When installing care should be taken in measuring the placement of the keyhole. Traditionally a strike was not used - a simple mortise was cut in the wood to accept the lock bolt.

2. Box Locks for lift lids as on blanket chests & boxes these locks require a strike to secure the box or chest lid.
