NEW NUT vs. OLD NUT
A new nut assembly for hinge and latch attachments on vista vents is now available. Part Number 20664430.
The new nut provides a better appearance as well as better sealing against water leaks.
If conditions such as loose hardware and water leaks at the hardware attachments are noted, replace the old nut and bushing assembly
with the new nut assembly.
The new nut has an integral seal and therefore no longer requires the use of bushings.
Due to the lower profile and improved appearance, the new nut should be used in all locations (hinges and latches) when service
operations on vista vents are performed.
