We carry 3 different series from Baldwin on our site right now, Prestige, Reserve and Estate, all very different. So, what is the difference?   Baldwin Prestige Series: The Prestige Series is on the lower end collection, quality wise. You can probably find this series at your local hardware store such as Home Depot or Lowes. If you are familiar to Kwikset, this series is comparable to that, what with hollow knobs and levers made of zinc. The entrance and privacy have thumbturns on the interiors to lock and unlock manually. The Handlesets are all sold as a package set including the exterior handleset and matching interior trim.   Baldwin Reserve Series: The Reserve series Baldwin offers is a much higher end quality made of solid brass. And all items are assembled per order and can take about 4 weeks before they are shipped, which is kind of a bummer, but if you are in no hurry, it€™s a great purchase. This series really is a nice quality hardware €“ comparable to Emtek, if you are familiar with Emtek brand. How it works is step by step you choose the rosette finish yadda-yadda-yadda, and if it€™s a handleset you choose the rosette as well as the interior knob/lever and the finish and whatever else. The Privacy locks include the pin lock on the rosette (rather than a push/turn button on the door knob/lever like most hardware) and the entrance will have a thumbturn on the inside on the door knob for locking and unlocking.  The backsets are adjustable, which makes it SO much easier and one less thing to have to measure.   Baldwin Estate Series: Baldwin Estate Series is completely customizable, meaning you can order whatever door knob with whatever rosette in whatever finish or in a split finish if you want, with different door knob/lever on each side- pretty much however you want it, this series can get it. They do have a few reconfigured sets, but mostly you just buy part by part and build the set exactly how you want. Although, this series can get a bit pricey, but again, this is good quality stuff. Any of the door knobs or door levers can be made into sideplates, multi point locks, rim locks, keyless locks, and mortise locks. Pocket door mortise locks are also found from the Estate Series. There are so many variations of latches, faceplates, and even door prep. Also, the Baldwin Estate series have concealed screws to make them look even better. There are over 17 different finishes and a ton of knobs, levers, and rosettes to choose from, so you can imagine the possibilities.
