The Baldwin Reserve Columbus is a sectional handleset built on a sectional platform, available in 8 hand-crafted finishes.
Sectional handlesets separate the grip from the deadbolt, so the two pieces sit independently on the door and the interior trim can be chosen freely.
Functions
| Single Cylinder | Keyed from outside with a thumbturn inside — the standard front door setup. |
| Double Cylinder | Keyed from both sides, for doors with glass within reach of the deadbolt. Rules vary by municipality — generally permitted where the room has another means of egress. Confirm with your local building department before specifying. |
| Full Dummy | Thru-bolt mounted with no latch and no strike. Uses a single cylinder interior with a non-functioning turnpiece. For the inactive leaf of a double door. |
Interior trim
Choose any Baldwin Reserve knob or lever for the inside of the door, paired with its matching rose. This style is offered with 11 interior options across 9 rose or trim styles — select yours at checkout. Interior and exterior must share the same finish; you can mix finishes between the two sides of a door, but each side should match within itself.
