Hi,
I have a rectangular above ground Intex pool.
I need to replace a couple of these caps (that have gotten brittle and cracked) but I have no idea what they are called so I don't know what to look for.
They are like caps for the vertical support legs...
See pics...
Anybody?

I think its a U-Support end cap for rectangular frame & oval frame pools. About $1.68. Going to be hard to see that your getting the exact match but maybe google "intex u-support end capt etc"
