The ASPEN SLIM fabric frame has a profile width of 19 mm. (.75 in.), making this single-sided SEG extrusion fabric frame the thinnest of them all. Less than half the profile width of ASPEN-40D SEG fabric frame, the outside finish is solid and smooth aluminum. This SEG fabric frame extrusion is especially lightweight, making it great for wall mounting. When installing the fabric graphic, the silicone beading can fit 12 mm. (.47 in.) deep and 4 mm. (.15 in.) wide into the trough of the frame. Not compatible with lights (cannot be backlit).
