Nostalgic Warehouse Prairie Backplate Privacy Mortise Lock Set

Nostalgic Warehouse Prairie Backplate reproduction skeleton key mortise locks are a great antique door knob replacement. The mortise box replaces most vintage skeleton key boxes found in older homes.  .

• Top quality, forged brass plates and genuine crystal knob
• Fits Doors 1-3/8" to 1-3/4" Thick
• 2 1/4" backset
• The interior mortise lock function has an active latch with a skeleton key locking mechanism.
• This lock requires a special mortise door preparation for the mortise case to fit into.
• We do not recommend this lockset on exterior doors. A deadbolt and passage function knob would be a more secure option.
• Note: If your door is not prepped for a skeleton key type mortise lock box, these door knobs will not fit. These antique reproduction knob sets are meant to replace old worn out skeleton key lock boxes, or you can prep new doors for the mortise box for that vintage feel.
