K-14 Floor Tile Bridge Structure Element for Connection 330x95mm

The bridge must be anchored using at least four K-20 screws. The bridge should be installed perpendicular to the line of the roof ridge so that it can be anchored in a total of four points, at least on two metal roof tiles. Use a screwdriver to screw in the screws, they are self-tapping screws. It is important not to pre-drill the hole for the screw, as this will reduce the contact surface of the screw with the sheet, thereby reducing the strength of the fastening. Remember that the washer under the screw head and under the bridge is slightly compressed. Tightening should not cause significant deformation. Screw in all screws at a right angle, otherwise the seal will not be correct.
