The ranat ek lek (Thai: ระนาดเอกเหล็ก, ) is a metallophone used in the classical music of Thailand. It is the smaller of the two sizes of Thai metallophone; the larger one is called ranat thum lek.
The ranat ek lek consists of flat metal slabs placed over a rectangular wooden resonator. It is played with two bamboo sticks with padded ends.
The ranat ek lek is very similar to the Khmer roneat dek.
