Frequently Asked Questions

Does this kit work on left-hand and right-hand doors?
The chassis mechanism can be oriented for proper latch alignment depending on your door swing requirements. Always verify proper handing orientation during field installation.
Will this kit fix a bottom rod that is scraping the floor?
Yes. When the internal springs or catch plates inside the top latch wear out, the vertical rod assembly loses its lifting tension, causing the bottom bolt to drag. Replacing the top latch resets the mechanical timing.
