Rectorseal83114 2 EZ 113B Trap Kit with Brush

Can someone tell me the length of the trap from bottom of U to the top of the highest horizontal pipe exit?

In our humid area attic condensate lines are usually insulated. am i ok not to insulate the clear trap so long as it's over the drip pan?

How broad is this one end to the other, horizontal size?

Is the assembly already glued, I need to re-orient the fittings?
