GENERAL INFORMATION OF ANCHOR CHAIN

● The inside length (grip or pitch) of one link is 4 wire diameters.

● The outside length of one link is 6 wire diameters.

● The outside width of one link is 3.56 wire diameters.

● The gauge-test length is the outside length over 6 links and equals 26 wire diameters.

● The weight of one links is about 3-1/3 times its wire diameter cubed.

● Doubling the wire diameter of one link multiplies its weight by 8.

● The weight of 1 linear foot of chain is 10 times its wire diameter squared.

● The length of a standard 'shot' = 15 fathoms = 90ft.= 1080'.

● The weight of a 90ft. shot = 900 times its wire diameter squared.

● Doubling the wire diameter of a 90ft. shot multiplies its weight by 4.

● Doubling the size of chain theoretically multiplies its strength by 4, in practice, by a trifle less than 4.

● The safe working load of chain is ordinarily assumed as one half the proof test.
