KAD-034 Kadee 30-Series No.34 Short-Length (Plastic Shank) Under-Set Standard-Head with Draftbox (2-Pair) HO Scale
This industry leading coupler features plastic standard coupler with metal knuckle, and #621 torsion centering spring and comes complete with #233 insulated draft gearbox and lid. The #34 Magne-Matic® Metal Coupler is designed mostly for body mounting with limited space either above or below the mounting platform, with or without Draft Gear Box Lid and with Draft Gearbox Lid either on top or bottom.
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.
