Brake-formed beam baffle cassette soffit

The patented WinLok™ accessible Beam Baffle Cassettes offer 100% downward accessibility. WinLok Beam Baffle Cassettes are made of brake-formed Aluminum, creating a plenum mask that transforms the space while leaving an open plenum for HVAC, lighting, and fire protection. Baffle profiles can be perforated for sound absorption or non-perforated for acoustically reflective vertical surfaces. No other manufacturer of baffles provides a range of widths and depths like Gordon. WinLok Beam Baffle Cassettes are easily removable for plenum access with the special access tool and are offered in a variety of colors and finishes for design flexibility.
