The mortise preparation provides a higher level of security than the 'L' style lock. The locks can be matched to the project hardware. Nystrom's doors accept a standard 1-1/8" mortise cylinder by most lock manufacturers (Best, Corbin, Russwin, Schlage, etc.). · D - Detention lock preparation. The detention lock preparation will accommodate several brands of heavy-duty detention deadbolt locks. The most common use for this option is in maximum security applications. MATERIAL OPTIONS These options are added to the part code after the size: (Example: ITK2424B) · B - Galvanized bonderized steel. This material is an economical choice for use where a corrosion resistant material is required. · S - Stainless steel type #304. With #4 satin polish finish. Stainless steel material is typically used in areas that require the highest level of corrosion resistance. It is also used in areas where a polished stainless steel look is desired. · G - Gasketing. Gasketing can be applied to the doorstops of the frame to provide weather resistance and reduce airflow between the door and frame. A UL listed smoke seal gasket is also available. · H - Continuous piano hinge. Occasionally, a flush piano style hinge is required on access panels for specification compliance. · M - Masonry anchors. Masonry anchors secure the panel when installed in masonry.
