The patented Hix Reten © frame is ideal for textile and graphic printers offering the most advanced technology. Square sidebars won't twist/warp like other frames and they clamp easily into any printer without adaptors saving you time and money. Hix Square sidebar frames can be taped and handled as wood or aluminum frames without special fabric protectors. No edge protectors are needed so you won't be replacing any fabric due to nicking and tearing because there is no exposed fabric wrapped around our sidebars. The Fastrax © system is the quickest "fabriic to frame" technique available on any frame. There's no pre-softening and corners can be softened at any time during tensioning or re-tensioning. Our color coded dual spline fabric locks easily in our continuous slot. No more damaged mesh from inferior end threading systems. The A Series for automatic printers allows up to 144 O.D. total perimeter inches at a tensioning rating of 50 Newton/cm. The maximum finished frame is 36" O.D. and the channel size is 1.5" x 1.5".
