Or you can easily build one yourself. I spent about 25 bucks on mine and it works great. The first one was supposed to be my proto-type and I was going to build a nicer one later but this one worked fine and looks halfway decent so I never got around to building the real one.

I just used galvanized steel poles and slide PVC pipe over them, I then purchased a $15 outdoor net from Acadamy and cut it to size.

One other thing you could do since you like the set you have; is just get a stick of galvanized pipe that fits into your deck, gut it down and slide the VB pole over it.

Word of advise, Instead of using galvanized pipe go the extra mile and use stainless steele that matches the set you bought. Yes the galvanized works however over time the chemicals will attack it. I'm sure you can locate a local fabricator who can cut the piece for you at a min cost.And yes the anchors are normally the same 1.5 inches but, above all else enjoy your new pool!!!!!!!!

Jenn,

We ordered our set from here too...

We have only used it a couple of times but it seems to be very sturdy. They are in The Colony so you can support a local business also!! ;-)
