Jumbo Big Blue Water Filter Housing Spanner

Exactly what I needed - and couldn't find elsewhere because the measurements are so often not given.

The item arrived quickly, and looks very substantial. but unfortunately was the wrong size. I’m very happy with returns policy. I will definitely give the seller five stars for their customer service.

Buy yourself a metal one. Costs more but will actually do the job. These just twist under load and snap, and I was using two doubled up.

Arrived on time but does not fit a 10 inch big blue filter housing. The key is slightly too large and when you apply any pressure to undo the filter the key slips.

Perfect fit for my Big Blue

Been battling with opening the housing on the filter for years, and this gadget opened it in seconds! Brilliant!
