CRL Polished Stainless Steel 7" Square Level 2 Bullet Resistant Speak-Thru

Introducing the Square Bullet Resistant Speak-Thrus, available in 5" (127 mm) and 7" (178 mm) sizes, designed to provide robust protection with Level 2 (.357 Magnum) and Level 3 (.44 Magnum) bullet resistance.
Featuring a polished stainless steel finish, these speak-thrus allow for natural voice transmission thanks to the air space between the glass and unit.
Constructed from heavy-duty stainless steel, they accommodate bullet-resistant glass, acrylic, or polycarbonate ranging from 3/4" (19 mm) to 2" (51 mm).
Additionally, barrel washers are included to cover screws, ensuring secure installation without over-tightening on the glass.
For optimal performance, glass fabrication is required, with the 7" model necessitating a 6" (152 mm) diameter hole.
