For making adjustable 1" wide straps. *Product cannot to be sold on any 3rd Party site such as Amazon, Etsy, Ebay or any other 3rd Party sites, unless approved by the manufacturer.* Dritz® adjustable slide buckles are pieces of hardware used by sewists and DIY enthusiasts to make adjustable straps for belts, purses, bags, backpacks and luggage. Use adjustable slide buckles to make straps that can be adjusted so that strap fits comfortably, or to convert bags from shoulder bags to cross-body bags (by allowing strap to be lengthened and shortened). The moveable center bar grips fabric and slides to one side to lock fabric into place. Ideal for thick, bulky straps. Use with other coordinating Dritz® hardware such as D-rings, rectangle rings, triangle rings and swivel hooks. For 1” wide straps.
