I've got a laminate foil dryer duct coming up from the crawlspace. I need to attach my dryer transition duct to the exhaust duct, but these really don't like to go inside one another since they're exactly the same size.

I managed to force on inside the other and secured them together with duck tape (If this is a bad idea, please let me know!). Are there better ways of doing this other than getting into the crawlspace and installing a new exhaust vent?

Duct Tape is good for a lot of things, except duct work! It will eventually dry up and pull away from the heat in the vent.

I would bend/dent one of the ends slightly so that it will fit easily inside of the other. Then I'd secure it with proper HVAC foil tape, followed by a clamp around it.

+1, duct tape will also fail in high temperatures since the adhesive will become soft. –  BMitch Mar 20 '12 at 14:20
