Many projects, such as tenant improvement work, call for sidelites to compliment the door assembly and add character and openness to the office setting. With our 20-minute rated wood sidelites, it is now possible to specify this feature in situations where codes dictate a fire rating. They are available in hardwoods such as red or white oak, cherry, walnut, mahogany, birch or maple, and are approved for installation in one hour walls 3 3/4” or wider.
