Abstract

Abstract A cantilever rack construction wherein a generally C-shaped connector plate embraces a flange of a column; threaded members pass through arms on the front of the connector plate and engage the column at or near to the root fillet; (which is the point of intersection of a flange on the column and the web of the column.)
