What size do I need? Karben Sports Family of Trainers Less than 10 min. assembly Each SkateRanger ICE is partially assembled out of the box to help make the final assembly a breeze. With the use of a mallet (even the heel of a boot can work!) and securing the included fasteners you're up and ice skating! Tough as Nails! Karben sources U.S. produced structural-grade PVC (sometimes called furniture grade) for all of its products. Unlike big-box store bought "plumbing grade" PVC, structural grade is substantially stronger and crack resistant. Resists UV-light damage One of the many benefits of structural-grade PVC is its ability to resists fading, or yellowing, of the plastic in direct sunlight. This UV resistance helps keep the material looking like the day you bought it for years to come. Made in the U.S.A. Proudly made in the USA, in Lenexa, KS (10 minutes from downtown Kansas City). Manufacturing facility, warehouse and operations out of the Meritex Business Park Underground Complex.
