Can I connect 62" Guide Tracks together for longer cuts?

Yes, you can attach a second 62" Guide Track to make cuts up to 112"-lonmg when using the Guide Tracks and Plunge Saw off the Project Table. You cannot use two 62" Guide Tracks on the Project Table. Guide Tracks are connected using Guide Track Connectors, which are sold in pairs.
