This is a real honest-to-goodness USA Tele sized 2 1/8" string spacing- NOT the Asian 10.5mm - which is very common with some other vendors. This can be used as a real string-though bridge like a genuine 1950's Tele bridge, and also has top-mount holes in the rear- so you can even use it on a guitar with no string holes. A great replacement for a vintage guitar or a great start on your Tele kit project!
