Alpina Manufacturing offers the Banner Grip stretching frame.
The Banner Grip stretching frame, by Alpina Manufacturing, is a frame system that not only serves as an aesthetic border but also is designed to tighten banners, remove wrinkles and waves, and hide edges and mounting hardware. Made of aluminum alloy and stainless steel, the Banner Grip can be used indoors or outdoors. It can accommodate various types of flexible and rigid substrates up to 1/16-inch thick, and can handle banners with raw edges, grommets, pole sockets, or hemmed edges, Alpina reports.
The frame measures 4-inches wide x 1.25-inches thick, and is available in any size up to 100 feet (large frames are sent in 60- to 80-inch sections and connect with pre-installed joiner straps). Available in black or silver. Ideal for building wraps, P-O-P displays, fine-art, décor, and more.
