Metal/plastic slide (strap adjuster) that creates easy, stable length adjustment on straps and belts without bulky knots. The central bar separates layers to grip and hold length securely. Works with webbing, cotton tape or leather on bags, aprons and pet collars. Built for repeat use in sewing rooms, classrooms, and studio production, this notion combines durable materials with easy handling. It installs with basic tools, aligns cleanly, and maintains a polished look after wear. Use it to streamline construction, strengthen stress points and add a professional, store-bought finish to garments, bags and home décor. For best results, test on fabric scraps and adjust needle, stitch length and tension to suit the base material. Great for kits, workshops and teaching new makers confident techniques.
