Abstract
A bracket for reinforcing a wooden joist provided with a hole for the passage of a utility conduit. The bracket includes a base wall having a central opening, sized to accommodate the utility conduit, for positioning against one side of the wooden joist. A pair of integral side walls extend at right angles from the base wall. A pair of integral flanges extend at right angles from the pair of side walls so as to be parallel to the base wall.
