Kadee Quality Products has been making model train couplers in White City, Oregon since 1947, and their magnetic knuckle couplers are the unquestioned industry standard for HO scale rolling stock. The phrase "convert it to Kadees" is shorthand among modellers for upgrading from out-of-the-box plastic couplers to something that actually works prototypically.
We stock Kadee deeply across HO. Couplers include the #148 Metal Couplers Medium 9/32" Centerset Shank 25-pack, the #153 "Scale" Whisker Metal Couplers Short 1/4" Centerset 2pr, and the #119-25 SE Shelf Whisker Metal Medium 9/32" Centerset 25-pair pack. Wheelsets include the Kadee 521 36" Diameter Ribbed Back Metal Code 110 Wheels. Trucks include the Kadee 511 Bettendorf T-Section Trucks with 33" ribbed back metal wheels. Spare parts include the Kadee 213 20-Series Gearboxes & Sleeves 24-pack, the Kadee 637 HO Truck Springs 18-pack (fits all HO sprung trucks except #513/555), and the Kadee 334 Uncoupler Gluing Jig (for installing #312, #321 and #322 uncouplers).
The Kadee magnetic uncoupling system — using #321/322 between-the-rails permanent magnets or #308 electromagnets — is what makes hands-off switching possible. Pair Kadee with our Parts & Accessories, HO Rolling Stock and InterMountain wheelsets. Ships from Oakville, Ontario. Free shipping on orders over $250.
