WTB square tubing pool fence

[muledeerarea33?]

Need to extend the yard since the puppy turned into a horse. I need 30-40' of square tubing standard pool fence. 8-10' sections preferred. Also need posts with the 4 bolt flange on the bottom, roughly 6. Prefer black but not picky, just gotta give the monster more running room while I'm away. Tucson or surrounding area. Don't get to Phoenix much. Thanks.
