System 45 - 2" x 4 1/2" Storefront Framing

	Download Details .pdf .dwg

Marlin storefront framing systems feature heavy wall (.080), rugged aluminum extrusions. Appearance and durability make Marlin the ideal choice for storefront performance.

Unitized assembly saves fabrication and installation time. This screw spline method utilizes two piece snap together vertical mullions, so the storefront arrives assembled at the jobsite ready to install.

System 45 has 2" x 4 1/2" and 2" x 6" frame members that are flush glazed with 1" insulating glass or panels. A glazing adaptor is available to accept 1/4" glazing if required.

System 45 offers door jambs, headers and thresholds to accept any medium or wide stile aluminum entrance package. Also available are 4 1/2" x 4 1/2" corner mullion, sill flashing and head compensation channel for header deflection.
