A time saving product to help you attach the fabric to your frame easily, and accurately. Includes three king size cloth leaders printed with precise guide marks and pin lines. It works great with our Fabri-Fast system, but also includes a Velcro attachment kit that can be used to secure the cloth leaders to your frame. 136" is great for King size frames while the 112" is great on smaller frames. If you have a crib sizw frame, you may need to cut down the 112".
