Hook twin tie plate is a special type of rail tie plate that can fasten the railway sleepers and railroad steel rails. The different design from common rail tie plate is that it is not for rail but only for frog. A complete set of frog consists of 2 point rails, 2 guard rails (also called check rails), 2 wing rails and the other accessories. They are always used in pairs between the frogs to ensure the tie spacing.

The plate has a hook for securing the rail, frog or other switch components to railway sleepers. It includes 2 main types: L plate with a hook and 9/16" tall; H plate with a hook and 15/16" tall. Their lengths are 23", 27", 31" and 35". They are 3/4" thick and usually made of hot rolled steel. It is a hot-rolled steel plate with several spike holes that are punched for track spikes to fasten. A forged hook is integral with the steel plate and used on the base of the rail or frog, which is much the same as the offset head of a rail spike in function.
