The Divider Bar is a specialized component designed to hide butt joints of adjoining mirror panels in various wall-mounted mirror installations. Constructed from aluminum with a satin anodized finish, this bar provides a clean and uniform transition between mirror surfaces, effectively concealing uneven edges that may occur in butt joint mirror configurations. The bar features a base width of 1-15/64", a height of 1/4" and a top width of 1/2", with a material thickness of 0.045". The total length of the bar is 144", allowing for extensive coverage across large mirror arrays. This divider bar is intended for use in residential and commercial mirror mounting applications where a finished, professional appearance is required at the junction of two mirror panels. The aluminum construction ensures the bar remains lightweight yet rigid enough to maintain its shape along the length of the mirror joint. Installation involves placing the bar over the butt joint to cover the gap and any irregularities in the mirror edges, providing a consistent look across the entire mirror installation. The satin anodized finish is resistant to common environmental factors, making it suitable for use in bathrooms, gyms, and other areas where mirrors are frequently installed.
