Inside corner transition may be made to compensate for the 2" gap.
The standard Ntrak ends are on one end of a transition module (the outside ends of the above module pair). On the opposite end (the inside ends of the above module pair), the tracks are swung to the rear at the same spacing except for being measured from the front of the module instead of the rear of the module. The two pin connectors on the outside ends will be wired as standard NTRAK connectors. The two pin connectors on the inside ends will be wired backwards. The wide pin will be connected to the rear rail and the smooth conductor of the zip cord and the narrow pin will be connected to the front rail and ribbed conductor of the zip cord. A module will have the either all male or all female connectors. A pair (of opposites) may be mated together when not needed for inside corner transitions.
The notches and tabs in the above picture are indicative of female and male connectors. The rail nearest the notch or tab is wired to the wide pin.
