Designed to be used with our 00/H0 Code 100 track systems (Ref nos. SL-100 and 102); also with 0 Gauge Bullhead (SL-700BH) and 0-16.5/0n30 (SL-500) track systems.
Design prevents adjacent rails from touching whilst holding them in alignment. Insulated rail joiners are required to provide electrical breaks where Electrofrog turnouts are used, for more details see our Wiring the Layout publications Nos 4 and 21.
