Identical to old Leviton 6250-11 dimmer socket.
"The dimmer switch specifications, circuitry, dimmer socket frame dimensions, wire tube nut and wiring tab locations are identical in size and placement to the original Leviton 6250-11 dimmer switch socket with my 1982 Chapman brass stand lamp. I rebuilt the original Leviton dimmer socket frame with the switch from the stock part in order to be able to refit in the lamp's tight specs."
