Deltana CF066U19 Window Lock Casement Fastener Black

Product Description

The DELTANA CF066U19 is a small casement window fastener finished in black. It mounts to casement window sashes to hold the window securely in the closed position, preventing unintended opening and reducing air infiltration. At 2.5 inches in length and 1 inch in width, this compact fastener suits windows where a low-profile locking mechanism is required. Weighing 0.1 pounds, it adds minimal load to the sash assembly. Glaziers, window installers, and general contractors typically specify this type of fastener for residential and light commercial casement window applications.

This casement fastener is suited for installation on standard casement windows in residential and light commercial settings. The small form factor makes it a practical choice for narrower sash profiles where a full-size fastener would not fit. It is sold individually and is appropriate for new construction window installations as well as replacement hardware projects where the original fastener has worn or failed.

Key Features

• Small profile at 2.5 inches long and 1 inch wide fits narrow casement sash frames
• Black finish provides a consistent look on dark-framed window assemblies
• Lightweight at 0.1 pounds, adding minimal stress to sash hardware
• Sold individually, allowing single-unit replacement without buying in bulk
• Low-profile height of 0.1 inches keeps the fastener flush with the sash surface

Compatibility

Designed as an OEM-style replacement or new-installation fastener for standard residential and light commercial casement windows requiring a small black-finish locking mechanism.

Installation Notes

Installation is typically performed by a glazier, window installer, or finish carpenter using basic hand tools. Before servicing or replacing any window hardware, ensure the window sash is fully closed and supported to prevent movement during fastener mounting. Follow the window manufacturer's recommended screw specifications for the sash material. Local building codes may apply to window locking hardware in egress window applications — verify compliance before installation.
