Introduction of wall filling device：
A plug for fixing the metal article on the surface of the wall is provided, which is a cylindrical structure. There is a hole on the bottom, and its outer wall is raised with long-strip and short thorns. The internal diameter of the plug should be slightly smaller than the external diameter of the thinner tail with concave thread of the metal handle of the article to be fixed. After the plug is filled with the metal handle, the external diameter of the plug is slightly larger than that of the metal handle. The adventages of the invention lie in fixing firmly and uneasily coming away after its being hammered into the wall.
Advantages: Pipe clip with wall filling device can endure reasonable pulling force when fit into drill hole of proper size (Please refer to test report). The clip can be removed using special devices if they are located too deep into walls. Since ordinary drop-in anchor cannot be removed once installed, they are usually screwed incompletely in normal use. Our patented filling device excels by its ability to be flexibly adjusted.
