Pro-Tip from Our Locksmiths: When troubleshooting a 9947/9947WDC that won't latch, check the top bolt first. Concealed rod devices rely on precise alignment of internal components, and building settling can throw off the top bolt engagement. A simple strike adjustment often fixes what looks like a device failure.
