Enclosure assy, brass, size 6x9. Submersible to 15 feet. Unless otherwise specified, this enclosure will be supplied with a depth of 5" inside as indicated by MIL-E-24142/3. The primary use of this enclosure is for a terminal box which is specified to be 4-1/2" deep inside. If the shallower depth is acceptable, a slight savings in cost can be expected because of the higher volume of usage. Other depths are also available on special order.
