Baldwin 6504009 – Frequently Asked Questions
1) My doors are pre-bored to the standard 2-1/8 inch hole. Can I still install Baldwin Estate knobs or levers?
That is exactly what the Baldwin 6504009 spring assist door adaptor is for. It retrofits any door pre-bored to 2.125 inches so Estate Series knobs and levers can be mounted in the existing hole. If your doors carry the industry standard 2-1/8 inch bore, the adaptor is required, not optional, so order one per opening along with the trim.
2) Will the 6504009 adaptor work with a keyed entry or deadbolt function?
No. The 6504009 adaptor covers full dummy, passage, and privacy functions only. If the opening needs a keyed entry, this is the wrong part for it. Use it on interior and non-keyed doors, and specify a different mounting solution where a keyed lockset is going in.
3) Do I need a specific rosette size when using the Baldwin spring assist adaptor?
Yes, and this catches people out. The rosette or escutcheon has to be 2.625 inches or larger to cover the adaptor. A smaller rose will leave the adaptor body visible around the edge. Check the diameter of the Estate trim you are pairing with it before you order.
4) Is this Baldwin adaptor suitable for a commercial building or is it residential only?
Baldwin lists the 6504009 as a residential part, and it sits in the Estate Series line. For apartment interiors, single family, and light-duty residential openings it is the right fit. For a commercial opening carrying heavy traffic or a code requirement, specify commercial-grade trim instead of retrofitting Estate hardware.
5) I am matching new Baldwin levers to doors already bored for standard hardware across a building. How many adaptors do I need?
One per door leaf getting Estate knob or lever trim, wherever that door is bored to 2-1/8 inches. The 6504009 does not change the door prep, it adapts the Estate mounting to the bore already in the door, so a fleet of existing standard-bored openings can all take Estate trim without re-boring. Confirm each opening is a dummy, passage, or privacy application, since those are the functions the adaptor supports.
6) What exactly is the Baldwin 6504009, a lock or just a mounting piece?
It is a mounting adaptor, not a lock. Model 6504009 is the spring assist plate that sits behind Estate Series knob or lever trim so it can mount in a 2-1/8 inch bore. It provides no latching or locking function of its own, so you order it alongside the trim and latch, never instead of them.
7) Is the Baldwin 6504009 adaptor metal or plastic?
Steel. The adaptor is built on a steel substrate, which is what carries the spring assist load behind the knob or lever.
