Swimming pools blog

I have an old - let me repeat old - above ground pool. I have no idea
what brand it was as I bought the house and the pool had no
documentation with it. I am looking for the “caps” that go on the
top rails at each intersection. The ones that were original to the
pool were broken when we got the pool. We since went to a local pool
supply store and bought some parts that are two pice and say “no
diving” on them. They work well but they too are starting to break.
I wanted to shop around for these parts as the place we go sells them
for 15 dollars each which for two pieces of placstic seems excessive
to me. Imagine the cost involved in replacing all of them! Anyone
got any idea where I can buy these type of parts online?
