Anyone know of a local supplier that would have the ipe? I need a piece that is 10' long, 4-5 1/2 " wide, and 1 1/2" high. I appreciate any help you can give. (I need to make a threshold for the shop door that is impervious to moisture, even water, and can withstand a vehicle driving over it at infrequent times. If anyone knows something that would be better, I'm all ears!! Can't find aluminum thresholds over 6' in length) Jim
