This is an aftermarket product imported from overseas. These are locking tuners made in the USA size, Kluson style. They should fit Fender Japan and Fender USA necks. The spacing from the center of one peg post to the center of the next is set to approximately 119mm. (Inexpensive Japanese/Asian-made necks are about 124mm, so they can be installed, but there will be a gap in appearance.) It's a no-name brand, bulk item, but I think it's a well-made product. These are perfect for those who want to try locking tuners but don't want to lose the vintage look. They look like Kluson tuners at first glance, and offer the benefits of stable tuning and easy string changes – a two-birds-with-one-stone solution. They are a 6-in-line type, suitable for Stratocasters/Telecasters. The color is nickel. Please check the various dimensions in the images.
