The new Hoop Tech koozie clamp, offered by GSG, is the fastest, easiest way to hoop and embroider on any type of can insulator, including foam-back polyester, Neoprene or collapsible fabric. This flat-window clamp can be rail-mounted onto any popular embroidery-machine brand, including ZSK, Tajima, Barudan, Happy, SWF, Melco and Meistergram, among others. This versatile clamp comes with a bracket that mounts directly onto the machine drive bar in the same way as a cap driver. Machine-specific adaptors bolt to the clamp body and are used to attach and adjust the clamp to fit an embroidery machine. The sewing area measures 2.75″ x 3″. Made of stainless steel, it does not leave hoop burn.
