Was pretty much as advertised with enough fittings to make it work and blanks for the ports not required. Is the same height as the older box I replaced but internally is higher to fit the current model Rule pumps.

Simple replacement for the one that cracked and leaked. The loose mounting flange and the hose adapters allow many options for installing. Easy access to remove lid for cleaning and maintenance if necessary. 4 stars because Directions were not clear on having to cut plugged end for shower drain. No adapter for that size so you slide on and use hose clamp just like original sump box.
