A round hole is factory drilled in the end of the log which is to be joined to the post. At the factory, a keyway slot is milled into the post.
A polypropylene key spline similar to the True North butt spline is installed in the hole in each course of log and inserted into the key shaped slot in the post.
Asphalt impregnated foam tape is used to wrap the two piece spline to ensure an airtight seal in keeping with the True North 25-Year "Zero" air infiltration warranty.

Advantage:
This technology is used by True North to butt a wall to an existing wall as well as a post. This system provides the first and only efficient method of having angles in a log wall other than the normal ninety degrees. This technology is especially useful in creating desirable prow fronts without the unsightly crossing over of each course of logs. |
