only 2 left
This starter pack contains a fret of 22 AC7/3 delayed action autocouplings for use on 7mm scale layouts. Also included are 2m of NSW7 nickel silver wire, 1m of SIW7 soft iron wire, and two 7MAG permanent magnets. The recommended minimum radius curve in 7mm scale is 4ft. For operation down to 3ft radius, use the MP7 mounting plates. They also have the added advantage of making the couplings easier to fit. The actual size of the fret is 103½ x 138½mm; it is etched in 0.018" brass. Each coupling is 42mm long and 12½mm wide. The magnets are 41mm long, 7½mm wide and 4mm deep.
