Adjustable T-Square

[Joseph Crivelli]

On American Woodshop Episode 1910 Outdoor Accents, Scott Phillips uses a black metal T-Square.
The blade of the square has a slot cut down the middle in which the head adjust and locks.
Can anyone identify this ruler?
I've searched in vain for this tool.
Thank you!

If it was 4" long then it was a drywall T square, if it was smaller then I think I saw something like it at Woodcraft.

I can't help identify the T-square, but I also noticed it on the episode mentioned by the OP. It is black in color and shaped like and about the same size as a drafting table T-square.

Thank you all for your responses to my question.

After identifying the T-Square in question, I decided that this tool was not what I was looking for.

I decided that the Woodpeckers 24inch Woodworking Rule togetherwith the Pinnacle 2" Rule Stop will give me the type of ruler I want.

I have Woodpeckers 12", 24" & 36" woodworkers rule with their 2" rule stop and it is awesome.
