The NANZ No 7800 series latches are the first to combine rare earth magnets and pneumatic springs. Unlike coil or leaf springs, pneumatic springs provide constant resistance resulting in an impressively consistent action. What’s more: they are infinitely adjustable to accommodate door knobs or lever handles of any size. As the magnetic latch passes the magnetized strike it snaps into the pocket. The No 7840 and No 7845 versions feature a privacy function activated by a thumb turn. Since the strike requires no lip and the latch is not beveled the latches are non-handed thereby simplifying specification. These unique features also allow the 7800 series latch to be fully concealed when the door is closed. Note that when specified with steel jambs, a lipped strike will be required. The latch combines an adjustable bevel 6” x 1” faceplate and a 2-1/2” backset. Compatible with all surface mounted trim, the 7800 series may be used on any project where a traditional full mortise set would otherwise be specified. Comprised of stainless steel and brass components, the latch works well in sea-side environments. As reassuring as it is impressive, the overall performance of the 7800 series is an extraordinary sight. We encourage one to schedule a demonstration with one of our local experts. All Nanz plated and patinated finishes are available. Please see our advertisement. The No 7835 is shown here with the No 2504 lever. US patent No D709,347 S.
