Standard, the OS saws up to 11’6” (3.5m) long. To mill logs 18½ feet (5.6m), add one 7’ (2.1m) extension. To mill 25½ feet (7.8m), add two extensions. Each extension bolts permanently to the end of the log deck. Additional log rest/dog clamping assemblies sold separately.
If you have a trailer equipped sawmill, and you add this extension, you must also add the Subframe Section and Support Legs
Note: Maximum of one extension permitted on the trailer-equipped model.
