These metal side release buckles are designed to work with 1" webbing and straps. Featuring an easy one-handed release, our side release buckles are great for backpacks, fanny packs, sling-bags, and more. The spring load closure ensures no accidental release, while the strapping connections allow for easy cinching the strap for adjusting length. The smooth design of this ALL-METAL side release buckle provide a beautiful finish along with solid strength and durability. NOTE: Sold individually, one per package. Every 1-inch hardware piece has a 1-inch opening for attaching strapping. We recommend covering the strapping with a coordinating fabric in order to make a truly custom look for your project. All relevant ByAnnie.com patterns include instructions for how to do this and use your fabric efficiently.
