Regular price $4.69 $3.99 Sale


This industry leading coupler features an all metal standard coupler, and #634 standard centering spring and comes complete with insulated draft gearbox and lid. The NO.5® Magne-Matic® Metal Coupler may be mounted with the included #242 HO Scale Universal "Black Box" Snap-Together Insulated Gearbox & Lids.

We managed to purchase a bunk package of Kadee #5 with the #634 standard centering springs and including the #242 Snap-Together draft boxes, are offering these at a reduced price, still the same quality, just less packaging and instructions are provide below at the links online. The quality of the #242 Snap-Together draft boxes allow the modeler to assemble the complete coupler assembly without the worries of it coming apart during installation. We think you will like the change too!

The 148 Whisker® Coupler is equivalent to the NO.5® Metal Coupler.
