Block Frame

  • The block frame provides a variety of attachment and installation options
  • Windows can be installed in wood/steel frame openings using optional fins, or in masonry openings using installation clips or jamb screws
  • Block frames may also be used in window replacement projects without removing the existing frame or damaging the exterior

Block Frame with Offset Fin

  • The continuous offset nailing fin is designed for use in new construction with thin exterior claddings like stucco, thus allowing the window to be located more to the interior
  • When the offset is not required, a standard profile fin is available (Shown below with dashed lines.)
