This is the support rod for fixing the steel wire.
② Draw the fixed position and length of the support bar on the railing. Rod.
(3) Look at the section of the sawed support bar. The material is aluminum alloy, which doesn't look very thick.
(4) Because the railing is round, it is fixed on the side of the railing with dovetail wires, which is more firm;
⑤ Wind the steel wire on it. The corners are simply cut at right angles, which is not nice. I propose a 45-degree angle saw to achieve the effect of "touching the angle" similar to paving bricks. Unfortunately, the installer always saws at right angles.
⑥ Pull the horizontal line. The height above 1.6 meters needs to be fixed by pulling a horizontal line. In fact, because the installation of the alarm needs to form a loop, the steel wire must go to the end and come back. Therefore, the window with a height of 1.47m is also horizontal during actual installation.
⑦ Tighten the steel wires one by one and fix them with screws.
Lift the cover plate and fix it on the rivet gun with rivets. The reason why we don't have to attack ourselves is because thieves dare not screw it off with a screwdriver. Very thoughtful. Because the aluminum alloy cover plate material is not firm, the rivet gun does not tighten the rivet until the rivet core is pulled off, but twists back and forth, exposing a sharp rivet core outside.
Pet-name ruby because there is no 45-degree angle touch process, so the effect at the corner is not very good. I don't know how other installation companies install it. Maybe I'm too perfectionist. But the handling of details best reflects the technical level, doesn't it?
Attending with cross clamp fixed horizontal steel wire and vertical steel wire. The pliers used are very special, which are specially used to clamp cross clamps.
