Customers find the adjustable tool universal for opening fuel fillers. They say it fits the Groco lid perfectly, and has two different size pins. Customers also say the bronze deck spinner is adjustable and has 2 pin sizes to open any and all deck fill pipes. Overall, customers are satisfied with the adjustability of the tool.

5.0 out of 5 stars A MUST HAVE ITEM!!
Reviewed in the United States on April 1, 2024

This spanner is an absolute MUST HAVE tool for boaters. It's fully adjustable as far as the span and it has two different size pins (located on opposing sides of the tool) so it's pretty much a universal fit tool for opening your fuel filler caps, water tank, and holding tanks. I bought two, one stored port and one stored starboard.

Well cast and assembled. Pins are tight in the bronze. The hinge is smooth with no slop. It gives that last bit of leverage needed to loosen sea strainer lids, etc.

5.0 out of 5 stars Must have to remove strainer covers
Reviewed in the United States on September 19, 2023
Verified Purchase
I have used one of these for many years to remove the AC strainer cover to clear grass etc. on my 1999 SeaRay Sundancer 40 ft boat. Well, I sold my boat and left the tool for the new owner. Our new 2004 SeaRay Sedan Bridge boat also has Groco sea strainers, so I’m repurchasing another tool. This is the perfect tool for that job. I would definitely recommend and buy again.

5.0 out of 5 stars Same as at West Marine but at half the price!
Reviewed in the United States on October 17, 2023
Verified Purchase
I went to West Marine for something else then happened to check out the scanner wrench for removing the cover of various raw water filters on the boat. It was $49 at West Marine! That seemed a lot for a simple tool, even if was brass. I went to Amazon and found what appears to be the same tool for virtually half the price!
