Ideal for modellers wishing to use the accessory with PECO turnouts. It will be especially useful in providing the means with which to mount a PL-10 Turnout Motor above the baseboard. The simple assembly of the base coupled with the omission of the spring (which is not required as PECO turnouts already "lock" into position with the over-centre spring), makes the PL-12X the best choice for this arrangement. And the pack is great value, with two bases provided.
