DN Forestay for wood or aluminum masts are made out of 5/32 in. 1x19 wire with a Race Lite adjuster. The adjuster is 7 in. long with ten positions for adjustments. The pin hole is 1/4 in. and we recommend using 3/4 in. long pull rings. The wire is fixed with an eye end to connect to the adjuster at one end, while the other has a fork end to connect to the mast.
