We produce self collar for downpipes

The halves of the collar are connected by single seam, then propaivayut tretnikom. Rebated compound can be replaced by water drain directed limb, which primarily rivet by a rivet 2-3, having a diameter of 2-3 mm, and then sealed.

Depending on the size of the auditory its windows covered with one or two paintings. Before you begin to manufacture paintings, you must perform crates measurements to determine the diameter of the bottom of the window, the length of the half-cone po.konku, the length of the half-cone on the slope.

Then, in accordance with the received size is drawing the window with his hands (a front view and a side), which is cut by roofing sheet taking into account the allowances for seams and overhangs and harvested two paintings.

Collar dormer consists of one front and two side aprons, harvested in accordance with the specified dimensions on a workbench and using a mallet-mandrel rod.
