Many times installations dictate the need for a door, or pair of doors, with sidelites on either side. In the past if you used a Header on top for your Overhead Door Closers, you had to adapt a different extrusion next to your Header to secure the top of the sidelites. CRL has developed a snap-in insert with a glazing pocket that snaps in on either side of the doors. This allows you to use one continuous Header with the center fabricated for the doors, and the sides fabricated for fixed sidelites. Glass is secured in the extrusion with the provided Top Load Roll-in Gasket. To secure the bottom of the fixed sidelites, use our UC38 Series U-Channel.
