Abstract: A connector for use in forming a joint between pieces of finished lumber features interconnected sleeves having respective open ends facing in different directions at outer ends of the sleeves opposite interconnected inner ends thereof for receiving ends of respective pieces of finished lumber. Each sleeve has four sides, two of which are defined by opposing side walls that are each flexible relative to a third wall interconnecting the two opposing side walls so that the opposing side walls are movable toward and away from one another to selectively change a width of a fourth side of the sleeve to accommodate variation between different pieces of finished lumber. A fourth side wall portion on each of the opposing side walls extends toward the other side wall to present an area through which at least one fastener is passable into the respective piece of lumber.
