A closure assembly is provided that includes first and second intersecting members such as a rail and stile. The rail and stile are engaged with one another forming a butt joint, preferably a corner. Male and female keys are respectively secured to the rail and stile with the keys forming a dovetail interlocking relationship with complimentary tapered surfaces. A fastener is received by the keys to expand the tapered surfaces forcing the rail and stile to be drawn into further engagement with one another at the butt joint. The interlocking tapered surfaces produce a stronger joint and eliminate any gap that might result at the joint as the threaded fastener is installed. The door is assembled by securing the male key to the rail. The stile is aligned with the rail and the second key is inserted into a pocket in the stile. The male and female keys are interlocked and a fastening element is installed into the keys to expand the keys and draw the rail and stile into further engagement with one another.
