the best thing about this easy fit radiator floating shelf is that there is not drilling involved as the brackets provided that you easily screw on  under the shelf are designed to fit between your radiator, and another good thing is, no matter how your radiator is shaped,  these brackets can be bended with force, to fit, like i did, and they are just perfect, and because they are raised from the radiator they do not warp, you can also put rad foil under the shelf it self to reflect heat, i am so happy with my shelf, i am very happy
