9 In Locking Chain Clamp, 3-3/8 In Max. Opening is rated 5.0 out of 5 by 4.
Rated 5 out of 5 by from Worth the investment Kioti tractor OEM filters are installed very tight and then coated in paint.A cheap knock off from those auto retail store broke on the first tug. $0 dollars in the trash can.My local NAPA dealer ordered this model for me. Installed wrench one hard solid tug and filter was loose, 10 seconds done!.Nothing beats quality for getting work done.I would recommend this to any tractor owner who performs their own maintenance.

Rated 5 out of 5 by from Great when you need it! I find many uses for this, but the best is doing pullies on cars. Wrap the OD of the pulley with a rag or strip of rubber (old inner tube works here) and then lock the chain around the pulley. Wedge the handle against something solid and work on the nut.Also works for turning shafts a bit, aligning exhaust joints, etc. Easier at times (and less damage) than a pipe wrench or pliers.

Rated 5 out of 5 by from Pipe fitter/pipe welder I cant even begin to describe the importance or practicallity of these babies. Two chain grips and a piece of 2x2 angle iron and who needs a fitting table. For the guys rolling out welds attach 2 180 degrees apart and they make a perfect mechanism for turning the pipe.
