This is a very large and heavy 18” alloy pipe wrench, and it’s also pretty old as it has a patent date of 3-5-18!
Its jaw teeth show little wear, the moving jaw is in good condition, and its knurled thumb wheel gear operates easily. It measures 16.5" long (completely closed), even though it is marked 18" on the wrench, and the jaws are 7/8" wide.
Weighing a hefty 7 lbs., it’s in very good condition overall for a working antique tool considering its age! Made to last in the USA by the Trimont Mfg Co in Roxbury MA!
