the lid it snaps back down pivoting relative to the attachment plate and the fittings to rest in the lowered position the bottom bracket 14 that is adapted for cooperation with the double fitting top bracket discussed above does not need to include a fitting for connection to a port because both inlet and outlet fittings in such an embodiment are positioned at the top bracket the bottom bracket need only be a support system for the bottom end 52 of the filter for such embodiments the base 54 and its post 56 do not carry fluid or convey fluid to conduits or other filters or vessels but rather serve for support alignment and securement of the filter the base 54 portrayed in fig1 and 2 includes a post 56 that may be received in an indentation in the bottom of the filter for alignment of the filter in the base but in an embodiment in which the filter top end 42 includes both inlet and outlet ports 44 46 the indentation is not a port and the indentation and therefore the post are not in fluid communication with the filter the bottom bracket 14 has a rear attachment plate 60 for attachment to the vertical wall and two spaced arms 64 64 u2032 that extend out from the plate 60 pivotally connected to the arms 64 64 u2032 is the base 54 with a bottom wall 66 and a side wall 68 surrounding and defining an interior space 70 for receiving the bottom end 52.
