What minimum bearing length is commonly required at the ends of engineered wood floor members unless the manufacturer specifies otherwise?
a.1/2 inch
b.About 1-1/2 inches on wood or metal (and more on masonry), per the manufacturer
c.4 inches minimum always
d.No bearing is needed if hangers are used
Explanation
Engineered floor members typically need on the order of 1-1/2 inches of end bearing on wood or metal (and more on masonry or concrete), following the manufacturer's tables, so the reaction is safely delivered. A 1/2 inch is too little, a flat 4-inch rule is not universal, and hangers still require adequate seat or nailing capacity.
