A system providing a secure lockbox methodology for protecting sensitive information is described. During manufacture, the female belled end is sequentially formed over a Rieber style gasket and then over a ring shaped casing member having an inner circumferential groove formed on its inner circumferential surface. The control includes an SCR connected between a full wave rectifier and a coil of the solenoid, with gate current removed from the SCR to commutate the SCR after a predetermined time interval after power is applied.
