1/2" Gold Aluminum Screw Post Extensions are excellent in making photo albums and scrapbooks longer so you can fit more pictures. They have a gold color anodized coating on the extension to give them the richness effect of the gold exterior. This extension is 1/2" long and has a 3/16" diameter. They fit perfectly into all of our aluminum screw posts. So if you want to add just a 1/2" to your project try our extensions.
