LARGE Chain from Royal Navy Minesweepers Some interesting history...as you may or may not know, all fittings onboard a Mine-Sweeper must be non-ferrous or non-magnetic and therefore made of brass, bronze or aluminum. This is to avoid triggering magnetically activated mines. External fittings that need to be strong, as well as, non-magnetic are always bronze, even the chain and anchors. This particular chain has links that are 6" long x 3 1/2" and about 1" thick. This chain is has a nice patina state and is in superior condition. This 6" link section is the LARGER chain used on board the mine-sweeper. This section of chain would be perfect for decor or hanging custom nautical lights. This chain is double link and is a section of approximately 31 feet long. We have a few more sections of polished and not polished chain. Furthermore, we have some LARGE Bronze chain in our other items. This section is Super heavy and will need to be picked up at our warehouse or shipped truck freight!!
