I talked to Fleet Farm and they said that HT Enterprises makes the house for Lakes N Rivers and I ended up ordering Replacement Hub for Instashak Series Popup Tents. I haven’t received it yet but I am hoping it works because I only used the house 3 times and it has been tough trying to find replacement parts. It was only 9$ for shipping and the part so I am going to give it a try. If it isn’t compatible with my rods I will just order the rods for the Instashak and modify them. Good luck.
Here is the link to the part.
