CRL CDS3S Brushed Stainless Surround Sound Spacer Studs for Bullet Resistant Protective Barrier Systems

These CRL Surround Sound Spacers are designed for use with bullet resistant acrylic or polycarbonate. Spacers secure a secondary glazing panel behind a primary glazing panel to provide natural voice communication. Sold by pack of three stud sets.
Two different styles are available. The PB011, with square end caps, is used if you want to match other CRL Barrier Clamps (PB011 series are sold individually). The CDS3S, with 1-1/4" (32 mm) round end caps, is used if you want to add a different look to your application (CDS3S are sold three per pack). For a typical installation template, see the Technical Drawings for CAD101 or CLD103.
