It has a 1:1 design so you can place the marks for the mounting holes. Essential, because I hadn't installed another one. It has two adjustment screws, one for the force and one for the slowdown before closing, so the door doesn't slam. Sturdy metal construction. It has a hinge for the angle of the frame in relation to the level of the door. Basic, because my frame was at 11° in relation to the door. The brown color matched with everything.
