## Long description

The KM GROM KM103.R adjustment screw is a precision-engineered component specifically designed for the installation and vertical alignment of lightning protection masts. Compatible with masts measuring 3000mm and 4000mm in height, this hardware serves as a critical link in ensuring the structural integrity of lightning protection systems.
