Deltana CF066 Window Lock, Casement Fastener, Small

Screws are in the bag. Every Deltana CF066 casement fastener is packed individually in a poly bag with matching screws, so the fastener arrives finish-matched to its own mounting hardware. That matters on a finish like Oil Rubbed Bronze or Antique Nickel, where a generic zinc screw head would stand out on the sash.

A casement fastener like the Deltana CF066 is for a side-hinged window that swings, not one that slides up and down. It mounts on the sash stile and throws a lever or arm against a keeper on the frame to pull the sash tight to the stop. A sash lock (the cam-and-keeper type) is for double-hung windows where the two sashes meet at a check rail. If your window slides vertically, a casement fastener is the wrong part.

Eleven finishes on the CF066: PVD Polished Brass, Polished Brass, Brushed Brass, Antique Brass, Polished Nickel, Brushed Nickel, Antique Nickel, Polished Chrome, Brushed Chrome, Oil Rubbed Bronze, and Paint Black. If you're matching existing hardware across a building, the PVD Polished Brass is the one to look at where the sash gets weather or heavy handling, since PVD is a harder plated coating than standard lacquered brass.

Solid brass, not a zinc casting with a brass wash. The CF066 body and substrate are both brass, which is what you want on an operable sash that gets handled daily and, on a casement, sees outdoor air every time it opens. Cast zinc fasteners in the same shape tend to fatigue at the pivot; brass doesn't.

Commercial. The CF066 is classed for commercial service, which is the answer a property manager or hospitality buyer needs before standardizing it across a building's casement or cottage windows. Solid brass construction is the reason it holds up to that duty rather than being a residential-only trim piece.

Size. The CF066 is Deltana's small casement fastener; the larger sibling in the same family suits a heavier or taller sash where you want more leverage and a bigger footprint on the stile. Pick the small CF066 for narrow sash stiles and lighter casements, and step up in size where the window is tall enough that one small fastener won't pull it flat against the weatherstrip.

Sold by the each. The CF066 unit of measure is single, packed individually, so you can buy exactly the count you need, one fastener per window opening. That suits both a single sash repair and a multi-unit rollout where every window takes one.

Paint Black is one of the eleven CF066 finishes, alongside Oil Rubbed Bronze if you want a dark finish with warmth rather than a flat black. Both are stocked on the same small casement fastener, so you can match the black or bronze door hardware already on the job without changing part families.
