Screw 20 has preferred embodiment of the invention, there is a tapered head, which receives a flanged washer shown at I0 a base casting preferably integral 22, and a gasket 23 adap-ted to -be drawn down and impervious, of generally rectangular shape. into sealing contact with an upwardlyl projecting vA plurality of adjustable feet II are positioned flange 2lil formed upon the casing member I 6, '2,408,942 Thus when screw 20 is tightened, the casing will be firmly held upon the frame i5, and the at taching means is adequately sealed and pro tected. The casing is also formed in its upper part with an opening for receiving grommet 25 which pro vides a close internal fit with a cylindrical level casing 26, suitably fastened by screws 21 to the 4 price valuations. Such magnifying lens is re~ ceíved within a metal frame piece SEI which is formed Iwith inwardly extending lugs |22 adapted to pass through apertures formed in recessed flanges |23 integral with casing I5.
