Well, w/o knowing more about what your doing (type of wall, what's conduit, what's wire mold), distance, etc., etc.), I can't help you directly. BUT, it's not a total loss.
I'm a bit confused in that your Message Header says Wiremold product installation. Yet, in your post, you talk about conduit. Maybe I have a different understanding of wire mold. Well, in any event, go to Wire Mold.com, click the Do-It-Yourself Consumer 'picture', and away you go (for wire mold). Contact them with answers to the specifics like I mentioned and they should be able to help you. Other than that, perhaps others here may be of assistance.
