## Abstract

An extrusion profile and cap system is provided. The extrusion profile may be made of metals, polymers, ceramics, and the like. The extrusion profile may include an outer perimeter forming an internal cavity. At least one channel may be formed along the outer perimeter and protruding into the internal cavity. The cap is releasably attachable to the extrusion profile and may cover at least a portion of the channel. The cap may hide bolts, screws, angle bars, wires and the like within the channel.

## Claims

### Claim 1

An apparatus comprising:
a first extrusion profile and a second extrusion profile each comprising an outer perimeter forming an internal cavity, wherein a channel is formed on a first side along the outer perimeter and protruding into the internal cavity, and at least one opening into the internal cavity is formed on a second side, wherein the at least one opening is formed by a first end ledge and a second end ledge, wherein
the first end ledge and the second end ledge of the second extrusion profile comprises a clip releasably secured to the first end ledge and the second end ledge of the first extrusion profile; and
at least one cap releasably attached to one of the first extrusion profile and the second extrusion profile covering at least a portion of the channel.

### Claim 2 (depends on 1)

The apparatus of claim 1, wherein the outer perimeter of each of the first extrusion profile and the second extrusion profile forms an opening in between a first edge and a second edge leading into the channel.

### Claim 3 (depends on 2)

The apparatus of claim 2, wherein the first edge and the second edge each comprise a protruding lip, wherein the at least one cap comprises a clip, wherein the clip engages the protruding lips of one of the first extrusion profile and the second extrusion profile.

### Claim 4 (depends on 1)

The apparatus of claim 1, wherein the at least one cap comprises a first cap releasably attached to the first extrusion profile and a second cap releasably secured to the second extrusion profile.
