FIGURES 13 and 14 illustrate a sink structure 125
wherein a sink member 127 having a flat outwardly pro

In all forms of the present invention it will be appar

nested engagement with the underside of the rim fiange but
nevertheless substantially spaced from the outer marginal

an extension from the rim iiange. Further, the retaining

ably centered with respect to the counter top opening and
while substantially precluding horizontal lateral displace

degree of resilient adjustment movement of the sink rela

This is advantageous to accommodate temperature differ
entials, slight plumbing imposed stresses, and the like.
Another feature of advantage throughout all forms of
the invention resides in that the retaining finger structure
is economically made from strip stock, and in the forms
of the invention shown in FlGURES 7 through 14, all of
the flange and channel components are similarly adapted
to be constructed as rolled or otherwise shaped strip stock
sections. Moreover, in respect to the forms of the inven

respect to oversize or undersize formation of the counter
