I spent 45 mins wailing on a deck access cover till I went online to find a wrench because I knew one existed. Fair price based on the 45 SECONDS it took me to loosen the siezed access fitting once it was in my hand. A small cheater pipe was needed because the handle is a little short.

Overpriced

Holding tank cap was stuck. After many attempts and slip ups, I managed to loosen it. It did the job, however it is not worth the cost

      Comments about Groco Spanner Wrench:

      Nice wrench to loosen and tighten Groco lids on the sea strainers. Much better than using slip joint pliers and busting knuckles up. I ended up returning the spanner wrench when I found it $7.00 cheaper a mile away in a private hardware store.

          Very Necesssary Product if you have Groco RSW Starianers

          Comments about Groco Spanner Wrench:

          Without this tool, opening a Groco RSW strainer to clean it, is very hard. Takes a large Channelock or pipe wrench or the like.

                    The store was out of them but the staff said they would be getting them in next week and they came when he said they would.
