Trappa Poster Frames feature snap-edges, which easily open from the front to allow for quick and easy, graphic changes with no tools required. This sleek framing system features a set of spring-loaded aluminum extrusions mounted to a high-impact polystyrene backer, and frames are available in a variety of sizes and in black or silver finishes. All frames come standard with clear non-glare lens, fully assembled, and ready to hang. Custom sizes are also available.
