Don-Jo 350-626 – Frequently Asked Questions

1) What size is the Don-Jo 350 window lock?
The Don-Jo 350 window lock measures 2-5/8 x 15/16 inches. That is the footprint you have to fit on the sash or the frame rail, so measure the flat area you plan to mount on before ordering, especially on narrow aluminum or vinyl sash where the rail can be under an inch wide.
2) Is the Don-Jo 350 window lock steel or a pot metal casting?
Steel. The 350 is a steel-bodied window lock, which is what you want on windows in schools, warehouses, and multi-tenant buildings where a cast zinc lock gets snapped off. The finish is applied over the steel body.
3) What finishes does the Don-Jo 350 window lock come in?
Four: 605 polished brass, 613 oil rubbed bronze, 619 satin nickel, and 626 satin chrome. Those are standard BHMA finish codes, so if the door hardware in the building is already 626 satin chrome or 613 oil rubbed bronze, the window locks will match it without a special order.
4) Is the Don-Jo 350 rated for commercial use or is it a residential lock?
Commercial. Don-Jo lists the 350 as a commercial window lock, and the steel body is the reason: it is intended for office buildings, schools, healthcare, retail, and multi-tenant residential rather than for one window on a house.
5) I need to standardize window locks across a whole building. Can I get the Don-Jo 350 in one finish across every opening?
Yes, each finish is ordered as its own item, so a property manager or MRO buyer can pull the entire building in a single code, 626 satin chrome for example, and keep every window consistent. All four finishes are the same 2-5/8 x 15/16 inch steel lock underneath, so the fit does not change when you switch finish.
6) How is the Don-Jo 350 sold, single or in a pack?
Shelf packs of 10. That suits the way these actually get bought, a contractor doing a floor of windows or a facility stocking a maintenance shop rather than replacing one lock. Order in multiples of 10 when you are pricing out a job.
