Made of Stainless Steel, using Metal Sintering Technology.
**We recommend that the installation of the part should be made by a professional since the spring pressure makes difficult to insert the part and tightening the screw at once. Also, the hole in the frame should be perfectly clean before installation. Fail to do that, could break the part or alter the shape.
The original part, (cylinder), is made of plastic, a very weak plastic that breaks apart sooner than later. That part does not match the almost indestructible material of the frame. My design is made of stainless steel, using the 3D printing technology known as Laser Sintering, not breaking and no corrosion, guaranteed!
Please ask any question before ordering.
