KD SideLight Frame A common problem with the installation of a sidelight opening in buildings is transporting the complete frame unit to the opening. Ceco Door is pleased to announce the KD SideLight Frame. This is a drywall sidelight unit that can be assembled and installed at the opening without having to weld the frame pieces together and transport them to various levels of a building. There are no more concerns of fitting the welded frame in the elevator or through doorways of a building. The Ceco KD SideLight Frame is designed to use common hand tools for installation in a matter of minutes in a rough opening. The complete frame bundle can be carried to the specified opening and installed in a very short time, saving both labor and transportation cost.
