The BS-7025 Board Support Brush is a silver-finish channel letter and sign cabinet component designed to hold sign faces, panels, or boards securely in position within a frame or cabinet. Supplied in bags of two, each brush measures 2.75 in. in height and 1 in. in width, making it suitable for standard board retention applications in fabricated signage assemblies. Constructed in a silver finish, these support brushes provide consistent contact pressure to keep sign faces flush and stable. Their compact profile allows installation in tight channel letter returns and shallow cabinet depths without interfering with internal components or LED strip layouts. No certifications, compliance listings, or warranty terms are confirmed in the available source data for this product. Contractors and sign fabricators should verify suitability for their specific application prior to installation.
