Linear fixture electro-mechanical joining

A light fixture system, comprising:

• a first light fixture that includes a first fixture wire harness coupled to a first electrical connector mounted to a first joiner, wherein the first joiner is attached to the first light fixture;
• and
• a second light fixture that includes a second fixture wire harness coupled to a second electrical connector mounted to a second joiner, wherein the second joiner is attached to the second light fixture;
• wherein the first joiner and the second joiner are configured to slide towards each other and each include at least one set screw configured to be tightened through at least one slot to apply axial force between adjoining light fixtures to make electrical connection and tighten a joint between the first light fixture and the second light fixture, the at least one slot being located underneath a light source circuit board to allow access to the first and second joiners after the adjoining light fixtures are lifted in the ceiling;
• and
• an optical element configured to conceal the at least one slot allowing access to the first and second joiners.
