Title: finger jointed dimensional lumber


Yes, finger jointed lumber manufactured for structural applications has the same properties as "non-jointed." Here's a link to an FAQ on the AWC website that will give you more background information:

List, I have 2x10 rafters @16" o.c. (spf#2) for a project and now
apparently the contractor cannot find the 26' long rafters. They would
like to use finger jointed rafters. Do these finger jointed rafters
have the same capacity as non-jointed? How is this determined? As I am
on "digest" mode, please cc to my personal email. Thank you in advance.
