Our magnet base is made of high-quality material. It is strong, rust-proof, wear-resistant, and exquisitely crafted with support, making it ideal for various everyday applications.

The rubber coating on the magnet helps protect its magnetic strength and prevents cracking or deformation during normal use, extending the magnet's service life. Additionally, the smooth surface helps prevent scratching on surfaces. This magnet features a countersunk center hole design, ideal for screw installation. Screws are included to assist in easy mounting.
