Get this pack of 12 Kadee Code 110 (0.110) 33mm ribbed-back RP-25 wheelsets for HO scale models. These wheelsets, commonly seen on steam-era rolling stock, are made to the strictest standards. They feature an RP-25 contour, non-magnetic metal wheels, and insulated needlepoint axles. Key features include a 'standard' ribbed back, accurate markings, high detail true to the prototype, smooth tracking, free-rolling RP-25 wheels, and suitability for both freight and passenger cars.

These wheelsets are easy to use. Just remove the old wheels from your HO scale model and replace them with these new ones. Make sure to align them properly. When handling, be careful not to damage the needlepoint axles. For maintenance, keep them clean by gently wiping with a soft cloth. Avoid exposing them to strong magnets as the wheels are non-magnetic. If you notice any rough rolling, check the axles for any debris or misalignment. With proper care, these wheelsets will provide smooth and long - lasting performance for your models.
