Kadee No.11 HO Scale Bulk Pack - 20 pair #5 (NO.5®) Metal Couplers - Medium (9/32") Centerset Shank

Compatible Gearboxes #213, #232, #234, #242, Most manufacturer molded-on gearboxes

Note: Some manufacturers now produce models with non-industry standard coupler pockets (molded-on gearbox). These shallower coupler pockets may require slight modification to the gearbox or coupler to function properly. If the model has a shallow molded-on gearbox, a #148 Whisker® coupler should be used instead of a No.5® coupler. The top of the #148 Whisker® coupler shank may be filed thinner to fit the shallower cast-on coupler pockets.
