Custom window opening control device installation
Four ASTM F2090-labeled window opening control devices were custom-fitted to non-standard projecting frames for a clean, code-focused result.

Project details
Careful work from preparation to finish.
A standard surface-mounted installation would not work on these projecting window frames. Each of the four mechanisms required its own recessed mounting location and carefully adjusted angle. We sourced the specialized hardware, prepared the mounting channels, installed and tested every device, then patched, spackled, and cleaned the surrounding surfaces. The finished installation uses devices labeled for ASTM F2090 and preserves the windows' full-release operation while addressing the required opening control.
