The #31 Kadee Magne - Matic Coupler is an outstanding product for HO scale models. It comes as a kit with a very sturdy plastic - insulated coupler. The #621 Torsion Centering Spring and insulated #233 Draft Gear Box add to its reliability. The 30 - Series Kadee Magne - Matic Couplers offer flexible body - mounting options, whether above or below the platform, with or without the Draft Gear Box Lid on the top or bottom. Each package contains two pairs of these high - quality couplers.

Using the #31 Kadee Magne - Matic Coupler is easy. First, choose the appropriate mounting position, either above or below the mounting platform according to your needs. You can decide whether to use the Draft Gear Box Lid and where to place it. The Torsion Spring should be mounted between the Coupler Spring Lid and Draft Gear Box, either above or below the coupler shank. When handling the coupler, be gentle to avoid damaging the plastic parts. For maintenance, keep it clean from dust and debris. You can use a soft brush to clean it regularly. Store the couplers in a dry place to prevent any corrosion or damage.
