Muntin Assemblies

Vertical muntins assemblies can be fabricated to divide any interior frame or create a corner between our framed blind units. View the sample drawing below. Typical units are made with 1-3/4” frame in clear anodized aluminum or options of bronze and dark bronze anodized aluminum or powder coated finishes. Frames are made to fit 3/16”or 1/4” tempered glass. Glass 5/16” thick can be used but requires a wet seal in lieu of gasket. Units come with 5/8” micro blinds in a variety of colors and a variety of control knobs for one or both sides of the blind unit. View our blind options and details below. These units come knocked down for field assembly and glazing with custom muntin assemblies. Glass available upon request. *Please note: Units are designed for interior use only.
