For your consideration are two NEW replacement belts for edelkrone Small and Medium sliders. These are M3 belts that meet or exceed the original factory edelkrone specification belts. They fit ALL edelkrone accessories such as the Steady Module, Target Module, Action Module, Motor Module (formally known as the slider module) Wizard Module, and all others. They are longer than required and may be cut to fit your slider's application. This is for the belts alone and does not include the edelkrone magnetic tabs.
