Can a Wiley ACE Acme Conduit Entry Box be used in place of a traditional combiner?

We are thinking about using the Wiley ACE Acme Conduit Entry Box with 4 inputs - Wiley ACE-4C Combiner 4 Input 64A 600V for a solar project.  What are the advantages and disadvantages of using an entry box like this vs. a traditional combiner box?


The Wiley ACE combiner box makes quick and simple transitions from USE-2 or PV array wire to conduit protected THWN-2 wire. The box features a compact two-piece UV resistant, NEMA3R rated, enclosure that allows ample wiring space and is compatible with any conduit type. The unique wire entry seals the enclosure even if entry slots are unused. Convenient side and bottom conduit drill out allow for easy conduit routing. The cover comes with captive screws for hassle-free assembly.

We used these Wiley ACE combiners on a recent 16 kW project.  They worked great.  Here is a photo from the install. So easy to use and cost effective.
