Accumate(R) Scale-Size Knuckle Coupler w/Draft Gear Box -- 12 Pairs

Improve the appearance and operation of your HO Scale models with the all-new Accumate(R) PROTO HO scale-size knuckle couplers. These magnetic couplers represent the first correctly scaled and proportioned replicas of the AAR type E coupler. Through the years, limitations of the manufacturing process resulted in knuckle couplers that are actually too wide, too long and too short when compared to the real thing. As a result, cars are spaced too far apart when coupled together and the standard mounting box (engineered to accept over-sized couplers) is wider than an actual center sill, making it impossible to detail this important area. Accumate PROTO HO couplers are correctly shaped and sized to overcome these limitations. When mounted in their own draft gear box, the length of the coupler provides scale striker to coupler pulling face distance, making any cut of cars, or an entire train, much more realistic. The draft gear box has been detailed to r
