Whisker® Coupler 30-Series Coupler Equivalent Gearbox.
Similar to the 30-Series Gear Box. Precision engineered to work with all Kadee® Whisker® Couplers.

Those of you that have a challenge assembling our 30 series couplers there is an option to look at. By using our #252 draft gear box, and an appropriate Whisker® Coupler is the equivalent to a 30-Series Coupler and so much easier to assemble. The Whisker® Coupler choice has the same last digit as the 30-Series Coupler you want to duplicate. The last digit in each of our HO coupler series are the same configuration in each series. Couplers ending in 8 like the #28, #38, #58, #148, and #158 all are medium length center set couplers and this applies to all the series. So when you get to the point where 30 series couplers are difficult to assemble use a Whisker® Coupler of the appropriate number and a #252 draft gear box. Also, the lid on the #252 snaps on the box to keep the assembly securely together.
