steel fins: S-532, S-540, S-832. Lengths from 2 to
12 feet. See p. 30.
JOINTS: Slip joint connectors align cover sections
which butt to one another, providing a near seam-
less joint. Use of telescopic accessories eliminates
the need to perfectly butt one length of cover to the
next. Critical linear and vertical tolerances are
eliminated because telescopic assembly absorbs
misalignment that might result from uneven floors
and walls.
