Twin pack of Niagara bifold runners that fit into the frame, remanufactured to the exact dimensions of the original parts, these are a common failure point for this type of shower enclosure and hard to source. Please check the dimensions in the picture to be sure these are the same as your original ones, I do have a different version in my listings also. If you need a different type than I already have message me on eBay messages and I’ll get back to you as soon as I can
