Hunt Magnetic Couplings ELITE - Close Coupling - 10 Pairs for NEM Sockets - TT:120 Hunt ELITE Couplings For TT:120 Scale:With our new ELITE TT:120 couplings you can never worry about polarity & formations never again, much work went into the Magnet Technology in these new couplings to allow the work of dual polarity's in one single compact coupling.
