HO Scale

The Whisker® equivalent to the NO.5® coupler is the #148.

Newer HO models with Bachmann EZ-Mate, Athern's McHenry, Accumate, Wather's Proto Max, or other makes of knuckle couplers will most often use our #148 whisker® coupler as a direct replacement. Be sure to check the coupler heights regardless.

Our #118 SF and #119 SE double shelf couplers are two totally different types of couplers and are made to actual scale. The #118 SF coupler looks over scale but it is not, it looks this way because it's simply a larger prototype coupler. Both couplers are fully functional and will not slip up or down out of the opposing coupler. Although they are not designed to compensate for rough or bad track, many modelers use them on their longer rolling stock rather than fixing their track.

We have two sizes of HO couplers, "scale head" and "standard head". Scale head, like the #158 coupler, are smaller and close to actual scale size. Standard head, like the NO.5® coupler, are a bit over scale. Both sizes are completely compatible.

We do not make "offset" scale head couplers as they are simply too ugly.
