This kit has 3 types of "half-sets" of Axles/Screws for Bauer / Hi Lo Inline Hockey Skates. Please note: They only include enough hardware for 1 skate. If you need to replace the hardware on both skates, you will need two of these kits. Kit Includes: 4 x Round Axle + 4 Round Screw for plastic Bauer FLEXLITE Frames. 4 x Round Axle + 4 Round Screw for metal Bauer / Mission / Hi Lo Frames (Jr sizes usually use these) 4 x Square Axle + 4 Round Screw for metal Bauer / Mission / Hi Lo Frames (Sr sizes usually use these) Include one Hi-Lo Bearing Popper skate tool. This kit does not include spacers. The other Hi- Lo Axle / Spacer Kit is the best to replace a full set of most modern Hi Lo skate frames like Kryptonium or CNC Aluminum. . Please send us a photo of your skates and we can ensure you get the right hardware the first time.
