This isn't designed to replace tent poles, it is a larger diameter pole designed to pitching tarps and single or double pole shelters. I'm not really sure where to find replacement tent poles.If you're wanting replacement tent poles, you need to contact the original manufacturer's warranty and repair department. When you call, be sure to have the tent model and (if available) model year available, as well as a good description of which pole needs replacing. Tent makers have hundreds if not thousands of different pole designs that vary by tent model.Be aware that some manufacturers make you go through an authorized dealer for the replacement pole.
