This frame is proudly made in the USA from 100% recycled structural plastic. This is undoubtedly the most versatile A-Frame sign frame in the marketplace with unlimited potential. The dual-channel end-cap design accepts 4mm and 6mm corrugated plastic or any 1/8” or ¼” substrate like dry-erase board, PVC, and even plastic-cored aluminum stock. The unique bungee-style center support makes this capable of capturing a wide range of sign-face sizes and can be set up in minutes. Frame can accept a maximum of 36 inch tall substrate if displaying as a double-sided sign (higher if only displaying a single-sided sign) and can be extended out to at least 96 inches long. Frame can also easily be weighted down for long term outdoor use. This frame is a great way to display a large menu board or a long barricade sign or anything in between.
