Kadee #148 HO Scale, Whisker Metal Couplers with Gearboxes, Universal Medium Centerset Shank

The next evolution of model train couplers starts and ends with the Kadee® Whisker® series of couplers. When we set out to improve upon the venerable No.5® we knew it had to be just as game-changing as the original. Often referred to as the "Whisker® version of the No.5®", the #148 has dethroned the classic #5 with an even longer-lasting and more reliable design. We took everything you loved about the No.5® and improved upon it. No more fumbling with centering springs. No more multi-piece assemblies. The Whisker® series of couplers is a true drop-in coupler. Use Kadee® Whisker® couplers in your next model and enjoy the most reliable and smooth coupling experience you've ever had. Always made right here in the USA with legendary Made In America quality. The #148 is interchangeable with the No.5®, #28, #58, #118, #119, #158, and most manufacturer's Medium Centerset OEM knuckle couplers. For a #38 equivalent use the #148 in a #252 Gearbox. #148 is also a direct replacement for most Bachmann On30 couplers. Package Includes: (2) Pair #148 Whisker® Metal Couplers - Medium Centerset Shank (2) Pair #242 Snap-Together Gearboxes & Lids (2) Spare #622 Knuckle Springs 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. Use the provided insulated gearbox or insulated #28 coupler. #148 Coupler Specifications Shank Length Medium - 9/32" (center of mounting hole to back of coupler head) Shank Offset Centerset Mounting Height 29/64" Centerline 25/64" Trip Pin Height 1/32" Head Style Standard Centering Spring Whisker® Knuckle Spring #622 Shank Material Metal Knuckle Material Metal Color Black Compatible Gearboxes #213, #232, #234, #242, #252, #262, and Most manufacturer molded-on gearboxes* #242 Gearboxes & Lids Specifications Material Insulated Plastic Dimensions 7/16" L x 5/16" W x 1/8" H Center Hole 2-56 Insulated Screws Color Black Compatible Couplers No.5®, #21, #22, #23, #24, #25, #26, #27, #28, #29, #58, #118, #119, #141, #142, #143, #144, #145, #146, #147, #148, #149, #153, #156, #158 *Note: Some manufacturers now produce models with non-industry standard coupler pockets (molded-on gearbox).

If the model has a shallow molded-on gearbox, the top of the #148 Whisker® coupler shank may be filed thinner to fit the shallower cast-on coupler pockets.
