Hanging frame assembly

An article for hanging on or being mounted to a support surface,

• the article comprising:
• a substrate having a first end and a second end;
• a first rail including a recessed channel that extends in a longitudinal direction;
• a first spline including a raised ridge that extends in a longitudinal direction, the raised ridge being configured for at least partial insertion into the recessed channel;
• and
• a first pair of end caps, each end cap of the first pair of end caps having an end walls and side walls that define a hollow interior, wherein each end cap of the first pair of end caps further includes slots that are formed in two of the side walls that are opposite one another;
• wherein each end cap of the first pair of end caps includes an off-centered protrusion formed along the end wall, the protrusion being received and frictionally held within one end of the channel that receives the substrate resulting in the substrate being pinched between the protrusion and the raised ridge;
• wherein in an assembled state, the first rail and the first spline are disposed adjacent one another such that the raised ridge is at least partially inserted into the recessed channel and the substrate is captured between the rail and spline and the first pair of end caps are disposed over opposite ends of the first rail and the first spline to join and hold the first rail and the first spline against one another with the substrate captured therebetween.
