KOCH ACOUSTICAL ENCLOSURES
KOCH acoustical enclosures control industrial noise, improve worker productivity and reduce workplace fatigue. They are engineered for long service life, offer maximum user flexibility, have a handsome appearance and meet OSHA requirements. KOCH enclosures are the most advanced and effective enclosures available.
KOCH enclosures and barriers are engineered for a lifetime of stand-alone strength! Load-bearing panels accommodate vertical and horizontal loading; no angle irons or separate framework needed.
