Maclock Log Connector is the easy way to keep ends of logs together. In some situations, such as garden edges, sand pits, top rails to fences, the ends of the logs move in different directions. Maybe caused by soil movement, soil compacting against the logs, plant roots or other forces. These connectors will keep the logs together. The connector is used for rounded surfaces.
