Power Unit found on Maxon's 72-25/30LM model and a few RCM models. This is a complete pump and motor assembly usually for gravity down gates.  If your gate is 72-25/30LM and is a power down model you may need part number 253473 instead.

What's Included?

The following items are included in this full power unit.  That said, you can purchase them separately if needed.  For our non-technical folks, the full power unit is the best option since it's basically a "plug and play" piece - remove the old one, insert the new one, connect, and you should be good to go.
