I acquired this eight from Marc Savinac in 2003.
The ISC is milled from aluminum alloy plate and then hard anodized. Mine is 170 mm. tall, 147 mm. wide, and 13 mm. thick. The rope hole is 61 mm. high and 74 mm. wide. The top center thickness is 13 mm. The shaft length and width are 65 mm. and 39 mm, respectively. The auxiliary hole is 15 mm. high and 19.4 mm. wide. The eye measures 20 mm. by 32 mm. The ears are 25.5 mm. long. My ISC eight weighs 208 g.
The front is marked with "I.S.C. Wales U.K.," an icon showing the strength test rigging and "kN 35," "RP 100," and "01D."
The ISC eight is a typical example of a milled aluminum rescue eight. Like all rescue eights, this one is too large and heavy for my taste. At least it is hard coated so that it will wear well.
