3/4" Antique Brass Extensions work great with our aluminum screw posts. They have a 3/16" diameter and will fit into a standard 1/4" hole punched or drilled. They are great for expanding a project that needs just a little bit more length. These extensions have a anodized coating in Antique Brass that gives them their wonderful color that will not scratch off. Try them today with your scrapbook, photo album, paint swatch and many more projects.
