Product Overview

Introducing the CRL No-Draft Speak-Thrus, specially designed for clear and audible voice transmission at ticket windows, box offices, and similar settings. These top-of-the-line units effectively prevent tampering from the outside and provide a barrier against drafts from entering the interior.

Each unit is thoughtfully packaged with gaskets and mounting screws, making installation a breeze on glass ranging from 1/4" (6 mm) to 1/2" (12 mm) thick.
