Product details

The Hayward BS74040 is a 40 mesh stainless steel strainer basket for the 4 inch Slant Top SB Series strainer. It is the genuine Hayward part.

Fine mesh, stainless build

A 40 mesh screen is considerably finer than the coarse baskets used to catch leaves. It holds back small debris that would otherwise reach the pump, which is exactly what a commercial installation wants ahead of expensive equipment. Stainless steel keeps its shape under load and does not go brittle the way plastic does after enough seasons of chemistry and sun.

When to change it

Baskets rarely fail dramatically. A split seam or a deformed rim lets debris slip around the outside while the basket still looks serviceable in the pot. Anything that gets past it goes into the pump, so the basket is worth inspecting properly rather than glancing at while emptying it.

Questions and answers

What people ask about this product, answered by our pool techs.

Which strainer does this basket fit?
The Hayward 4 inch Slant Top SB Series strainer.
What does 40 mesh mean?
It describes how fine the screen is. A 40 mesh basket catches much smaller debris than the coarse baskets used purely for leaves, at the cost of clogging sooner.
Is the basket stainless throughout?
Yes. It is a stainless steel basket rather than a plastic or plated one.
Why replace a basket that still looks usable?
Because a basket that has split a seam or lost its shape will pass debris around the edge without looking obviously broken, and everything it misses goes into the pump.
