#118-25 HO Scale Bulk Pack - 25 pair #118 SF Shelf Whisker Metal Couplers - Medium (9/32") Centerset Shank

In the late 1960s, the top and bottom shelf Type “SF” coupler was developed and standardized in 1970 for hazardous material tank cars. During this same period, the Type “E” coupler with a bottom shelf was developed as the Type “SBE”, and the Type “SE” top and bottom shelf came later on. The Type “SF” and “SE” couplers were standard for tank cars in 1975 and eventually became mandatory for hazardous material cars. Kadee® #118 Type “SF” coupler is a scale size coupler that, compared to the smaller Type “E” scale couplers, will seem way over scale, but it’s not.

• (25) Pair #118 SF Shelf Whisker® Metal Couplers - Medium Centerset Shank
