I hadn't heard of Baldwin before a trip to my local Home Depot. They've been around for while and traditionally make high end door hardware. By high end I'm talking three to four digits high end. I believe you can even design custom knobs should you desire. What drew me to these levers over the old standard is the (and I didn't know this before looking into Baldwin more closely) use of the "Estate Latch" which only requires 28 degrees of movement to open retract the latch. Great if you are older and find using standard levers difficult. An additional note is the weight of these levers. You're getting some serious hardware. I've replaced knobs and levers in the past, but they all weighed nearly nothing in comparison to these units.The first unit I purchased ended up having a mechanical problem. I highly recommend, though it may have been a fluke, checking the latch to verify it will retract flush to the plate. A tip when installing the lever is when installing the internal half of the unit to be aware of the position of the lock. The first one I installed end up shooting the lock out, but thankfully no damage was done as all I had to do was slide it in and turn it so it lined up with the internal mechanism.I really like these levers. I'm not sure if Kwikset bought Baldwin, but Baldwin uses Kwikset's SmartKey for lock re-keying. I plan on buying Baldwin for all of my future door hardware needs.If you want the information direct from the manufacturer here's the product link: (...)
