Voice Transfer Units

These units are designed to be incorporated at the bottom or side of the security window as required. The standard VTU consists of stainless steel blades (G1, G2, R1/S1) or aluminium angles (BR) cut to fit the width of the security window and with bolts to secure to the counter. The VTU should be of the same security rating as the glass. VTU’s are also available for a range of other applications including anti-contraband units for high security and institution use.
