The end walls I2 are provided near opposite

' walls l2 are interchangeable and in mounting and
securing the same to the top and bottom walls It
and I5 of the trough, a screw 34 is passed through
. one of said pair of holes 43 into a matching tapped
hole 45 in said walls It and I5. The screws M are
entered from the inside of the trough, and the
structure is thereby made tamper-proof when the
will be readily understood from an inspection of
Fig. 5. The end walls I2 are provided at the ex
treme ends of such trough or troughs, whereupon
the available or speci?ed meter or meters, such
as 21, 270 and 2100, of one or more makes and/or
types are mounted in position and the cover
members II ‘are fastened down over the respec
tive units. Thereafter the meter trim closure
elements I9, HM and I 92 are selected to accom
modate the outside diameters of the projecting,
encased clock-work mechanisms 2t‘ of each of
the said meters, and are set in place to seat
over the shoulders 28 of the several meters,
whereupon they are fastened in superposed rela
tion on the covers by screws 22 which may be
suitably sealed, as shown for example in Fig. 4,
after the installation is inspected and tested.
In the modi?cation shown in Fig. 7 the meter
support and meter support bracket of Fig. 2' are
omitted and the meter base or socket may be
supported by the back wall I32 of the trough or
cabinet element IOIJ. A screw 360 threaded into
said wall serves to ?x the meter base or socket
in place. In this embodiment the cover support
‘element 370, corresponding to element 37 of Fig.
2, is suitably attached to wall I38 as by spot weld
ing. I have also arranged to have the meter trim
ring I 93 seat on the cover support 316 and the
cover III superposed on top of it and sealing
