Type divided into brick walls, wood-paneled walls, decorative walls, glass walls, marble walls, these walls to screw size and spacing requirements are very stringent. User when installing wall LCD TV, you should pay attention to the different installation techniques based on different types of walls: 
    1, when ordinary brick wall installation does not require special tools and processes, just use percussion drill (note the drill diameter) punched in the wall, and then inserted into the plastic expansion tube, the product with screws, hang the TV can be. (Note: Different rack installation method is slightly different, as described in the specification or installation diagram) 
   2, Wall Wall divided solid wood and plasterboard walls. As long as there is 2cm thick solid wood, with a self-tapping screws directly mats fill the ring to fight. If the plasterboard walls, you need to choose the right anchor point, the first point of hanging art knife with a central location to drill a hole (in order to be able to go in his own finger size), then the hole on the rack put a 2cm thick long wooden slats, so that self-tapping screws through the gypsum board at the time of tapping into the wooden slats so that the force area increased. 
    3, the marble walls of marble and marble walls have divided the overall pattern marble. For the whole marble slabs, to use glass drilling. When using glass drilling must be while drilling, drill water side of the glass, so the glass drill bit burned out. Could be replaced if it is difficult to drill through the glass wall of the drill, drill half the impact drill, impact drill, but must be placed in the drill file, otherwise it will marble clefts. After the hole lay, you can install expansion screws, tighten up so far. For a pattern of marble,to be doubly careful when drilling because of a pattern of marble itself has lines at the top, slightly larger vibration force will cause cracks to expand. 
   4, behind the glass wall glass walls are brick walls and hoardings. If behind the glass walls are brick, in the selected location, first with a glass drill, but also need to drill into the glass while drilling while watering, selected bits of glass must be greater than the impact of the drill hit a brick wall, glass hole lay later, with the impact drill inside the brick wall. In order to prevent the screws put crushed glass, preferably a large selection of expansion pipe screw as filled circles. The thickness of the fill circle optional glass slightly thicker than is appropriate, and then tighten the screws. If the glass behind the wall, just use glass drill holes drilled glass, glass hole slightly larger, the drilled hole can be filled into the ring, and then tapping with a self-tapping screws, self-tapping screws must be selected + thickness than the thickness of the glass is still a little long planks.
