(a) frame members comprising:
(i) a first member;
(ii) a second member spaced apart from the first member; and
(iii) connecting members extending between the first member and the second member, wherein the first member, the second member, and the connecting members each comprise a front surface and a rear surface that form a front frame surface and a rear frame surface;
