#34 HO Scale 30-Series Plastic Couplers with Gearboxes - Short (1/4") Underset Shank
Note: The 30-Series Torsion Spring can be mounted either below or above the coupler shank, but must always be mounted between the Coupler Spring Lid and Draft Gearbox.
The #144 Whisker® Metal Coupler mounted in a #252 Snap-together Gearbox is equivalent to the #34 Coupler. The Whisker® Coupler mounted in a #252 Snap-together Gear box makes for simple and easy assembly.
It is not recommended to use a metal coupler directly on a metal surface or in a metal draft gearbox to avoid possible electrical crossover and shorting that may cause damage.
