The length of the handle is 187.5mm, with a distance from the centers of the screw at 74mm. To choose the correct dimension, depending on the size of the surface and the position/method (vertical, horizontal) where it will be placed, measure from the center of one hole to the center of the other.
The price refers to a piece.
