Check the listing for details. Circuitron 6100 RTM Remote Tortoise Mount. Condition: New. Listed at 19.95 USD. The CIRCUITRON Remote Tortoise™ Mount consists of a molded base mechanism to which the TORTOISE™ (not included) is mounted. An adjustable lever arm is fastened onto the TORTOISE™ output and drives a stainless steel wire inside a flexible teflon tube, much like a subminiature choke cable. This thin wire attaches to a compact actuator mechanism and is mounted beneath the turnout. It includes a spring wire and brass tube to transmit the motion to the points above. The mounting bracket (with TORTOISE™) may be secured in any position and up to 18" away from the turnout points—even above the layout inside a structure, if desired. The points actuating mechanism requires 1/2" clearance under the turnout sub-roadbed. The RTM is fully adjustable for all scales and brands of turnouts.
