The CRL Sharyn Frameless Pass-Thru Window will bring a modern appearance to what has been a traditional looking world of pass-thru windows. The "No Hole" Clamp-On Assemblies match the Header finishes, and allow height adjustment of approximately 3/16" (5 mm) that may be required due to field conditions. The Double Track Header has side walls that discreetly hide the Roller Assemblies, thus eliminating the need for unsightly valance covers. The Sharyn "Frameless" Pass-Thru Window is offered in three different two panel configurations of sliding and fixed panels to accommodate most any service condition. An optional Fixed Lite Header Insert is for the fixed side panel.A Thru-Glass Mounted Keyed Lock or Push Button Lock can be ordered separately for Custom Windows. The Push Button Lock is included on the stock window. Rubber Bumpers are included in each kit to assure soft closing of the window. 48" x 48" (1.22 x 1.22 m) 1/4" (6 mm) pre-glazed stock models are available when a quick solution is required to complete your job, or "Quick-Fab" Custom Windows are also available. Custom windows are available with 1/4" (6 mm) clear tempered glass, or unglazed.
