Dual DR's [RE-wrenches]

[jay peltz]

Hi John,

Also you can stack models of different sizes.  Trace doesn't advertise it but I
learned from one of the head engineers that you can stack a 1524 and a 3624.
With the large one for the loads of the house and the combined for the well pump.

I agree that they do work well for houses but I find that most people want the
"options" and so the SW.  I wonder where the compitition is for that one??
