A trench duct side rail having an upper section and a lower section, the upper section including a pair of spaced-apart downwardly extending legs and with the lower section being disposed between the legs. The upper and lower sections are axially off-set so that on one end of the side rail the upper section extends outwardly of the lower section and on the opposite end of the side rail the upper section extends inwardly of the lower section.

DETAILED DESCRIPTION We claim: 1.
In a trench duct: first and second elongated spaced-apart side rails each side rail having opposite ends; cover means mounted on said side rails; plate mechanism for mounting the trench duct over a subfloor; and each said side rail having an upper section and a lower section, the upper section having a pair of spaced-apart downwardly extending legs with the lower section being disposed between the legs and the lower section being connected to said plate mechanism and the upper section and the lower section being axially off-set so that on one end of the side rail the upper section extends outwardly of the lower section and on the opposite end of the side rail the upper section extends inwardly of the lower section.
2.
A pan trench duct comprising: first and second elongated, spaced-apart side rails, cover means and an elongated, rectangular-shaped plate mechanism for mounting the trench duct over a subfloor each side rail having opposite ends; each said side rail comprising an upper section having means mounting said cover means, a lower section, and adjusting means mounting the upper section on the lower section for vertically moving the upper section with respect to the lower section, the upper section having a pair of spaced-apart downwardly extending legs with the lower section being disposed between the legs and the lower section being joined to said plate mechanism; said plate mechanism extending between said side rails for use as the bottom of the pan trench duct; and in each side rail, the upper section and the lower section are axially off-set so that on one end of the side rail the upper section extends outwardly of the lower section and on the opposite end of the side rail the upper section extends inwardly of the lower section.
3.
A side rail for a trench duct, the side rail having opposite ends and an upper section and a lower section; and the upper section having a pair of spaced-apart downwardly extending legs with the lower section being disposed between the legs and the upper section and the lower section being axially off-set so that on one end of the side rail the upper section extends outwardly of the lower section and on the opposide end of the side rail the upper section extends inwardly of the lower section
