Square Bullet Resistant Speak-Thrus (SKU: N555C3) are available in 5" (127 mm) and 7" (178 mm) models with certified Level 2 and Level 3 protection. The air space between the glass and unit preserves clear voice transmission while spacing washers secure the glazing to the front and back plates. Constructed from heavy 11-gauge stainless steel with a polished finish, these square bulletproof speak-thrus accommodate 3/4" (19 mm) up to 2" (51 mm) bullet resistant glass, acrylic, or polycarbonate—ideal for high-security teller windows and secure transaction openings.

NOTE: Barrel washers to cover screws are included; trim them to prevent over-tightening on glass.
