by placing screws into holes 24 drilled through each overhang through the exposed panel edges formed by recesses 37 and 39 and wedged underneath their respective overhangs this method of adjoining the frames allows expending the dance floor to a large area such as a full room or a portion of it as desired completing the dance floor assembly are lower end trim panels 32 side trim panels 98 and an l shaped corner bracket 34 that seal the periphery of the dance floor trim panels 32 wedge lengthwise underneath the first overhang 38 while side trim panels 98 are configured to wedge underneath the second overhang 41 trim panels 32 and 98 may come in lengths that fit one frame or multiple frames most typically two or three this is shown in fig5 7 and 8 the corner bracket 34 fits in the corners of end frames 10 between the trim panels 32 and 98 that wedge under the first and second overhang lips the ends of the wires traversing the channels 16 and 17 each contain an electrical connector 28 at the upper end 77 of the frame 10 and an electrical receptor 88 at the lower end 56 in joining two frames longitudinally the connector of one frame plugs into a corresponding receptor of a second frame trim panels 32 contain embedded wires that have wire endings for attaching to receptors 88 contained.
