North American Bullet Proof’s glass SLTW Series sliding transaction windows were developed primarily as interior units. This window is ideal for customers that have varying degrees of threat depending on the time of day or circumstances. The SLTW unit is offered with aluminum, prime finish steel or stainless steel frames. These units are usually built with plastic laminate, stainless steel or solid surface (Corian) parcel shelves. Usually a MDT stainless steel deal tray is included. The SLTW windows are available in Levels 1-3 UL. These units arrive fully assembled and ready to lift and anchor into a finished opening, As with all NABP products we have vast experience customizing SLTW’s for unique requirements.
