The CRL Stainless Steel Speak-Thru provides natural voice transmission. Offset slots in front and rear prevent tampering from the outside, and stop drafts to the interior. Speak-Thru has a brushed stainless finish, and comes in two sizes. Two sets of screws accommodate glazing from 1/4" to 1-1/4" (6 to 32 mm) thick.

This speak thru now ships with two sets of screws, one suitable for 1/4" to 3/8" (6.4 to 9.5 mm) thicknesses, and another set good for up to 1-1/4" (32 mm) thicknesses that can be filed down to suit sizes in between.
