The No.006 Coupler is also designed to fit into n-scale trucks with Rapido style couplers. Just make sure the coil spring is available, as it is needed to steady the coupler parts.
However in comparison to the No.005 Coupler above it features a slightly elevated knuckle top to allow for a little more height tolerance between cars with body mounted coupler and cars with truck mounted couplers, as well as rolling stock from different manufacturers.
The hole in the knuckle section allows for insertion of a magnetized 0.3-0.4 mm spring hardened steel wire that can be used for magnetic uncoupling. However we’re planning for and just testing an uncoupling pick that will be produced via Shapeways.com too.
The 20-Pack offers 20 pairs of couplers for a total of 40 single couplers. Estimated price will be around 10,95 EUR via Shapeways Shop (plus shipping).
