21315 12-Inch Strap Wrench, 12" Handle

I bought this to remove the filters on my home filtration system. The long strap handles them with ease. I haven't tested it on anything truly difficult to remove, but it works perfect for this job.

I bought and used the strap wrench with one project in mind - to loosen the nut attaching a lawnmower flywheel to its crankshaft. I needed to do this because the shear pin had failed after striking a rock (which is what it is supposed to do to protect the motor). Needless to say the movement of the flywheel really cinched up the nut. The aluminum flywheel is about 6" in diameter and the cooling fins are a separate plastic piece so the only way to safely grasp the flywheel is with a strap wrench. I had to adjust the strap wrench a few times to get a good bite and even had to use an extension on the socket wrench on the 15/16" nut but I was finally able to loosen the nut and free the flywheel. I'm sure it was well over 20 lb-ft of torque. The bottom line is that this strap wrench worked admirably for my application and it cost far less than what a Briggs and Stratton strap wrench would have cost.

Item was a bit larger & heaver than expected & a little hard to use due to unfamiliarity with it, the include instruction was not very clear, but performed the task needed. It slipped a bit when used but eventually held well. In terms of utility it is a relatively heavy duty tool & for smaller diameter items, or enclosed spaces it may not be the best choice, for me it was ok. Cannot comment on durability.

It’s a great tool for overtight caps on car engines, such as different reservoirs: oil, engine coolers, etc, this “wrench” loosens and tightens them with no damage and little effort.

Review Addition: I'd received a question asking what the ad meant by: "Tube capacity: 9-Inches pipe capacity: 2-Inches." Good question! Best I can say is "ignore that". As I said below 'It worked perfect to loosen a super tight flywheel nut on an 8.5 inch dia. outboad flywheel.' As my pic shows the handle has "300MM-12 inches" cast into the handle. I say "ignore". It works great. (Old review below) OUTSTANDING! EXCELLENT QUALITY! ALUMINUM HANDLE. STRONG NYLON STRAP. DELIVERED FAST. FIRST JOB: REMOVE 8" DIA. FLYWHEEL NUT FROM OUTBOARD. NEEDED 18" BREAKER BAR/7/8 SOCKET & THIS TOOL. IT WORKED EXCELLENT. THEN FLYWHEEL PULLER NEEDED 18" BREAKER AGAIN, AND 12" EXTENSION ON THIS STRAP HANDLE. AGAIN EXCELLENT! FLYWHEEL SHAFT/SOCKET WAS RUSTED, WITHOUT THIS TOOL NO WAY I COULD HAVE GOTTEN IT OFF. I'VE USED "RIGID" BRAND BEFORE, THIS IS AS GOOD. I'M VERY HAPPY I BOUGHT THIS TOOL.

May work OK on larger pipes. I was attempting to remove an impeller from the shaft of a Goulds irrigation pump. The band would not grip and just slip around the impeller. The band is made of a slippery nylon material. Not the best choice. I'll keep it around for other projects, but I probably should have bought the rubber one.

This is a quality tool capable of solving difficult jobs far superior to the plastic junk sold at tool chain stores.

With so many different size automotive oil filters, this fits every one of them. No guess work involved.
