Rounded Steel Lock, doors hinged right

Rounded Furniture Locks are an economical style, specific to some 19th - 20th century furniture. Use on drawers and doors hinged on right.  These are an early style "machine" lock easily installed in mortises cut by routers or machinery. The lock has an angled selvedge edge seen on many furniture pieces from this time frame. Strike not included as not required.

This is a very reasonably priced lock, as such: locking mechanism is average, not as smooth as finer made brass locks, yet is serviceable. If using on doors please select according to side door is hinged on.

Helpful information on selecting and replacing half mortise locks.

• Backset- Distance To Pin: 5/8" If replacing an old lock, BACKSET SIZE is critical, as keyhole in lock and furniture must line up together.

Install Considerations

If replacing a lock, we suggest reading: What you need to know about selecting and replacing half mortise locks.

1. When using on doors: select according to side door is hinged on. This lock is for cabinet doors hinged on right.
   
2. When using on drawers: Keyholes are off-center requiring lock to be positioned accordingly.
3. Lock installs into a partial cut out in furniture. In closed position, lock is not seen. 

If replacing a lock: the backset measurement must be determined

• If you have original lock: measure distance between top edge of lock to lock pin in center of keyhole. This measurement is known as the backset.
• If old lock not available, determine backset by measuring: distance from center of keyhole (where lock pin will be) to top edge of drawer or side edge of door.
• The backset measurement of the replacement lock, must match backset measurement in original lock and/or keyhole location measurement in drawer or cabinet door.
