----------------------------Original message---------------------------- David: Two makers of hinge locks for file cases (vertical or flat files): Multi-Lock Inc. 2027 Harpers Way Torrance, CA 90501 213-320-6400 The make 5 lengths of hinges: 11, 21.5, 33.5, 45 and 56 inches. They look nice but the longer ones have too much play in them and bind easily. The shorter ones are fine and are inexpensive (about $10 I think). All hinge pins and welds are covered by a chrome plated channel, about 1.5 inch wide. McDowell-Craig Mfg. Co. 13145-T Firestone Blvd. Norwalk, CA 90650 213-773-3451 We don't have any of their "Swing-A-Way locking bars" in our library but I have seen them in use elsewhere and though they aren't as good looking as the Multi-Locks (not plated, riveting exposed) they are smoother in operation.
