NOTICE: The Texas weather emergency in February, in addition to the ongoing demand increase for pool products from the Covid pandemic, have caused industry-wide shortages on many products that most vendors expect to last late into 2021/early 2022. We're allowing items to be purchased so that customers who choose to wait will have their order shipped when product arrives. Many times there are long shipping delays on the few products we do have in stock. Please contact us to ask about availability. Live Chat and email will get the quickest response.

What are the dimensions of the: small & large clamp washers; clamp nut?
Stephanie M on Jun 10, 2020
Does the tension clamp assembly include the bolt? My Pentair filter #160301 needs just a bolt but I don’t see how the bolt can be removed from the clamp
