According to the plan drawn up by the committee supervising the manufacture of the shrine's grid of Aba Al-Fadl Al-Abbas (peace be upon him), and after the completion of the installation of the wooden structure, the works of linking the upper parts started by the the wood basis on which the golden frieze will be installed, and it is one of the important parts of this structure, which is installed with the same precision and durablity by which it was manufactured.
These parts, which take the form of S, are based on the upper column of the grid (the upper linking bridge) with a height of 34 cm in the form of pieces, four of them are pillars and others are limited between them, with an overall length of 580 cm, a width of 451 cm and a total perimeter of 2061 cm, installed by using a hidden technical way to link these pieces with each others and with the wooden structure using special tools to make it look like one piece.
The used wood was the the teak Burmese, which was imported from India and which is characterized by several features, including the resistance to various environmental conditions of moisture and others, the resistance of heavy weights and it is not exposed to insects such as termites or others. The raw wood was formed and cut according to the dimensions of the structure using special machines that were configured for this purpose under the supervision of the technical staff, cutting and working on it according to the required measurements, and the thickness, durability and accuracy of this structure are larger than the old structure.
It is to mention that the wooden structure of the holy grid takes the form of a parallel rectangles with a length (540 cm), width (412 cm) and height with the written bands' base, of 300 cm and consisting of:
1- Four corners' pillars, each column has a thickness of 20 cm x 20 cm and height of 350 cm.
2- Ten lateral pillars brodering the grid's knotworks with a height of 300 cm surrounding the structure and based on the four lower pillars that are linked to four others.
3- Four lower wooden pillars linking the corners' pillars from bottom, with a thickness of (17 x 16 cm)
4- Four upper wooden pillars linking the corners' pillars from up, with a thickness of (17 x 16 cm)
All these colins are linked according the particular measurements, though all wooden parts consists of one piece without resorting to linking works usying the "pressing" method to have large-sized parts, for fear of the opening up of the "pressed part" with time and also for more precision and durability.
