Is there an acceptable length of standard 12" truss (let's say Light Duty Tomcat Box with Plates) that can be extended past a point, assuming there is nothing hung on the truss past the point? I realize there's potentially a few other variables here, but figured there must be someone with some guidance, who would start asking questions beyond, say 8ft. Last time I looked at a truss spec sheet I remember seeing distributed load totals but nothing about cantilevered truss.
