A peripheral portion of a light frame construction building constructed from structural engineered wood components involves first, second and third structural engineered wood rim boards each having a cavity on an exterior-facing side and a substantially flat interior-facing side, with ends of the second and third structural engineered wood rim boards abutting each other to form a corner, and an auxiliary corner support affixed to, and within the cavities of, the second and third structural engineered wood rim boards.

A system and method for inhibiting oxidation of a metal lintel in a masonry wall. An anti-corrosion unit is built into the structure of the masonry wall above the lintel. The anti-corrosion unit has a reservoir housing that retains a volume of a protective oil. The reservoir housing releases the protective oil over time through dispensing holes in a first surface of the reservoir housing. The first surface of the reservoir housing is placed into contact with the lintel within the structure of the masonry wall. The protective oil is released onto the lintel along the contact interface. The protective oil coats the lintel, therein inhibiting oxidation of the lintel.

A system for traversing an opening of a construction element the system including a elongated housing with two extendable elements configured to reside at least partially within the housing. The extendable elements may extend beyond the housing and may include flanges or ledges which may engage the ends of a construction element, which may be a wall, and thus allow the system to traverse the opening of a construction element, such as a window or door. A coupler may be utilized to connect to a more than one elongated housing element to provide for traversal across even larger openings. The system may allow a user to easily manipulate the system to fit a plurality of openings and reuse the system a countless number of times.
