Description

15-1/2 in. x 7-3/4 in. x 3-1/8 in. hopper vent for glass block windows
The Clearly Secure Glass Block Hopper-style vent is designed to work with any 3 in. thick glass block brand. This nominally sized 15-1/2 in. x 7-3/4 in. vent is used in place of two 8 in. x 8 in. x 3 in. glass blocks when assembling a glass block window using individual blocks. The convenient size allows access to fresh air without compromising security. It may be used with either the mortar or silicone method of glass block assembly. The Clearly Secure 16 x 8 Hopper Vent can also be used in existing glass block windows to add a fresh air option. The included screen is mounted on a removable aluminum frame making screen replacement easy.
