Answer:
The UB-600 uses a clamp-on U-profile design that slides over the edge of the glass leaf, securing the lock armature plate firmly without requiring holes or drilling into the glass.
The UB-600 is engineered specifically for frameless architectural glass leaves where drilling is prohibited or impossible. It clamps directly onto the top edge of the glass panel using clamping screws paired with protective gaskets/shims, creating a rigid metal mounting platform for the electromagnetic lock's armature plate.
