The issue is that there is not an asset classification this can possibly fall under. After reviewing multiple internet sources and reading this IRS source, i would depreciate this using a 7-yr GDS classification.
IRS states that any property that does not have a class life and has not been designated by law as being in any other class should be considered a 7-yr GDS property class.
