Is this code talk for 'von duprin'? :)
Ha! No. At least, not specifically.
Full disclosure -- I work for Stanley Convergent Security, which is a sister company of Stanley Mechanical Solutions, which owns Precision Hardware. It should be noted that despite working for a "sister" company, I'm in no way incented to sell Precision over anything else. Generally, I sell what the customer asks for, assuming it's a quality product, and only provide recommendations one way or the other when asked.
Von Duprin makes fine products. They wouldn't be the name they are without being a good product. And, to be abundantly clear, they would fit within my recommendation above for "a good product".
But....
In my opinion, Precision is a better, more robust product. The caps of the bars are made from investment cast steel instead of stamped metal, and is a more substantial product than Von Duprin. The electrified devices are rock-solid. The devices come standard with a 5-year warranty compared to the Von Duprin's 3. The finishes are actual architectural finishes -- vastly different than Von Duprin in that regard as well.
Again -- while I think Precision is better, Von Duprin is a good product. Sargent is an OK product. And....that's basically where my list stops. :)
