Solid brass sash lock for historic double-hung windows
A sash lock does more than lock the window. On a double-hung, the right one pulls the two sash tightly together when you engage it, which closes the gap at the meeting rail and cuts down the draft. These do that, as long as the meeting rails are lined up properly.
They’re solid brass, all metal, with no plastic parts and no brass plating to flake off. The unlacquered finish means the brass ages and patinas over time, so it ends up looking like the original hardware on a historic home instead of a shiny new replacement. The curved design operates as smoothly as it looks.
What’s included
One unlacquered sweep, one catch, and four Phillips raised countersunk screws.
Dimensions
- Sweep: 2 1/2″ wide x 1 1/16″ deep x 3/4″ high
- Catch: 2 1/2″ wide x 9/16″ deep x 1″ high
The more you buy, the more you save.
