I work for a Christian school which had a floor installed in the gym made by Technoledge. I have an owners manual with the book that says it is an Excaliber floor. I have learned that this company is no longer in business. There have to be parts out there somewhere for this floor. Is anyone familiar with this company? Does anyone know where there might be some replacement parts for this floor? Any help would be greatly appreciated. If you want to e-mail as well as post on here, my address is email@example.com.
