Large-scale modelers (#1, A, G, F, and related gauges) often face coupler incompatibility when mixing equipment from manufacturers like LGB, Aristo-Craft, USA Trains, Bachmann, and others. Factory-installed hook-and-loop or varying knuckle designs lead to coupling incompatibility. Kadee® large-scale knuckle couplers solve this by providing an aftermarket knuckle coupler that is compatible across brands of equipment (when properly installed), while offering realistic appearance and smooth performance.
Choosing the right size Kadee® Coupler for your large scale layout.
Kadee® offers two primary sizes for large scale:G-Scale couplers: Larger profile suited to 1:22.5, 1:20.3, 1:29 models. These provide better coupling reliability on tight curves.

See kadee.com for comparison.
