These are N Scale replacement couplers for Rapido style couplings. These are shorter than the standard Rapido couplers by 2mm (0.078”) and can be used to bring rolling stock closer together with out causing buffer lock. Using two together will bring the rolling stock 4mm (0.157”) closer giving the impression of a connected corridor.
This set has 240 short couplers in a container. They are loose inside, not on a sprue.
The coupler head and tail closely match the Rapido standard and couples smoothly to each other and Rapidio couplers. The new coupler uses the existing spring in the Rapido socket.
The BS&F material does leave a rough finish on the on the sliding face but this does not affect the working of the coupler.
This particular coupings where designed for Graham Fairish's HST sets but will work with any rolling stock fitted with Rapido couplers.
Other lengths and quantities are available on request.
