Framatic Fineline 10 x 10" Black ultra-thin metal picture frames will hold some 10 x 10. There is no matting, just regular glass held in place by a very thin lip. Designed in Los Angeles decades ago, it still comes across as simple, clean and contemporary. There is no matting with it, but there are snap-in sawtooth hangers on the back to allow easy hanging. Frame is opened by means of two built-in latches that let you remove one rail so that the contents will slide out for easy access. Stocked in black only, the 10 x 10 is one of those hard-to-find sizes.If you have a photo or artwork that is square, but not 10 x 10, we can cut a mat for you to fit this size frame. It would be 10 x 10 outside, with an opening of up to 7 x 7" (gives you a 1 1/2" border all around). Just drop us a note on our "Contact Us" page for a quick quote.
