tion. The Whitten Model 10 is constructed entirely [
of solid steel stock except, naturally, the center
column. The inherent extra strength of steel in the
Whitten 10 allows us to design a truly cantilevered .
stair. Each tread is supported at the center column" .
by welded cantilevered tread supports. The hand- -_ (
rail is supported by spindles mounted in the center ...
of each tread. The solid steel and one-piece welded '
construction of the Whitten Model 10 makes a " ""
totally integrated staircase. ". " "" -

the criteria, Whitten 10 is the choice. This spiral "
staircase has our unique, thin-line, flat steel hand- -
rail and tread design that adds to the airy elegance .

clean lines of this proven cantilevered design bring .
a feeling of openness to any location. These stair-
cases are solving space problems in offices, ski
chalets, residential homes and institutions. Equally
adaptable to interior or exterior location, the M.,ode'
10 has found space-saving popularity from .,~!lar
playroom to attic den. The Whitten Modea i, is a
one-piece, completely welded, fully assembled ,
staircase ready for installation when you receive it. :
It won't loosen with wear even when subjected to'

stitutions. Factory assembly eand welding eliminates -
screws, bolts, center column joints and handrail
connections and ensures the s,'est, most rigid stair .5
