(b) Bevel edges of the section and top rail cutout area to a thirty degree angle (See figure 3-6).
(c) Tack weld section in place making sure there is a flush fit. Check to be sure that standard
measurements shown in figure 3-1 remain within the listed tolerances.
(d) Continuously butt weld section to top rail edges.
(e) Grind away any excess weld material on top or bottom edge of top rail which interferes with fit of
roof and side or end panels.
(f) Remove wedges and continuously weld roof and side or end panels to top rail.
(g) Clean and paint according to paragraph 2-4.
(h) Test for weatherproofness according to paragraph 2-5, caulk if necessary.
d. Replacement. Replace the top rail if it cannot be repaired by straightening, inserting or sectioning. The
replacement top rail must be identical to the damaged rail in length and profile.
(1) Measure standard dimensions indicated in figure 3-1. Measure between corner posts for dimensions of
replacement top rail. If standard dimensions are out of tolerance, be careful to obtain measurements for
replacement top rails reflecting correct standard dimensions.
(2) Use oxygen acetylene torch to cut welds holding the top rail to the corner fittings, roof panels and side or
Direct oxygen-acetylene torch away from corner fittings, corner posts and side and end
panels to prevent damage to an), of these parts.
(3) Remove the damaged rail.
(4) Grind smooth all cut edges.
(5) Remove old caulking which would interfere with installation of new rail.
(6) Measure and cut replacement rail to exact length.
(7) Fit replacement rail in place. There should be no more than 5/64 in. gap between the rail edges, the
corner fittings, and the roof and side or end panels.
