• bridging means connecting said horizontal and vertical members;
• a decorative surface affixed to said lattice structure;
• hanger means adapted to be affixed to said elevator cab shell wall interior and engagable with said lattice structure, swing arrester means mounted on said shell wall and engagable with said lattice structure to prevent lateral movement;
• said horizontal members having a channel slot for removable engagement with a claw member on said hanger means to provide vertical support;
• and said vertical members being engagable with said swing arrester means to prevent lateral movement, and wherein said vertical and horizontal members are made of an aluminum extrusion with a channel shaped cross section that provides both strength and portions forming said channel slot and a surface adapted to engage said swing arrester means, and wherein said horizontal and vertical members are made of an aluminum extrusion having the same channel shape with a relatively wide flat base and with shoulders on each side extending away from said flat base a relatively short distance compared to the wide flat base.
