To make the necessary construction yourself, you will need a standard wooden profile.

First mark the required height and width for the opening. Subtract about 30 mm from the height indicator. Measure and cut a pair of side rails. Prepare the top bar in the same way.

Take a special tool - a miter box. And connect with it the tops of the side racks and the ends of the crossbars, and then cut all the parts at an angle of 45º.

The peculiarity of the miter box is that it plays a big role in the formation of a cut of the required angle.

Remember that the crossbar on its smaller side, even after you cut the corner, should not be narrower than the width of the canvas, but, on the contrary, should exceed it by about 7 mm.

Join the upright and the crossbar so that their media are perpendicular to each other. Between them, you can pre-lay a connecting soft gasket, about 4 mm thick. Squeeze the bars and secure them with clamps.

Two holes are drilled in a long element perpendicular to the cut plane with a diameter of 4 mm. Through the holes, the joint is tightened with screws. It is advisable to coat the joint planes with carpentry glue.

Similarly, the second corner of the frame is pulled together. For temporary strengthening of the structure, it is recommended to install a removable jumper at the bottom.

To make the joint more durable, you can install a special dowel. To do this, drill a small hole and hammer a piece of wood into it. Before that, thoroughly grease both the part and the hole with special wood glue.

So, when the system is assembled, it's time to start installing it.

  • First of all, dismantle the threshold.
  • Then fix a wooden plank which is approximately 20 tmm thick and the width is identical to the door frame. Fasten it firmly with dowels.
  • Round the plank at the top and drive two dowels into the floor. Fasten the threshold. Make sure that its length is exactly the same as the width of the opening.
  • After that, start fixing the system itself. Drill three holes into the uprights on the sides, retreating about 10 cm from the edge and center. Make exactly the same recesses in the crossbar. It is important that the distance between them is the same.
  • Insert the box into the opening. Use the holes to make markings in the wall. Take a hammer drill and drill holes for the dowels. Fasten the last piece with screws.
  • Check that the uprights and crossbeam are set vertically and horizontally. If something is wrong, then you can slightly adjust their positions with gaskets, wedges or specially twisted screws. If you decide to use the latter, be sure to pay attention to how much their hats stick out, push them deeper into the box.
  • In some cases, the thickness of the structure itself may not be enough. In this situation, extras will save you. They must be fastened in the same way as the bars.

    The extension should have exactly the same thickness as the timber, it should not be higher than the surface of the box.

  • Do not forget to put a special sealant in the grooves over the entire area of ​​\u200b\u200bthe structure. If there are no special recesses for this purpose, then simply glue the sealant to the surface of the bars.

After you have finished with the installation, you can proceed to the last, cosmetic stage of work.

  • The gap in the area of ​​\u200b\u200bthe wall and the opening must be well sealed with mounting foam. Do not save on this useful material. The strength of the structure and its throughput depend on how well you cope with this stage.
  • When the foam hardens, you can move on to the next step. Cut off the excess and carefully sand the surface.
  • Proceed to the installation of platbands. Cut off the strips in the amount of three pieces. Two of them will need to be placed on the racks on the side, and the rest - placed on the crossbar. Make sure the tops of the planks are cut at a 45º angle. Fasten the parts so that the side cut coincides with the end of the structure and the other cut is located along the wall. The platbands must be well attached with screws, the heads of which are best hidden in the wood.

In the course of work, you may have gaps: in the area of ​​​​the platband and the general system, the extension and the beam, between the beams and the platbands. You should not panic and consider yourself a would-be master, everything can be fixed.

Fill these gaps with a special wood putty. This material is applied in dense layers, two will be enough for you. First, close the gap well, and then level the mixture and apply a little more composition for the fortress. When the treated surface is dry, use sandpaper and sand the area well. At the very end, you need to install the loops on which the canvas will hold. Use a chisel to make indentations in the right places and secure the parts with screws and an electric drill.
