National Mfg N185-447 Zinc Sliding Door Center Latch

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N185-447 is a zinc sliding door center latch designed for bi-parting wood sliding doors. It uses a cam action mechanism combined with an adjustable hook to pull both door panels tightly together at the center meeting point. The zinc construction provides corrosion resistance suitable for interior door hardware applications. This latch is intended for wood sliding doors at least 1.5 inches thick and is installed by carpenters, finish contractors, or experienced DIYers working on barn-style or pocket-style bi-parting door systems. Each package contains 5 units.

This center latch is suited for residential and light commercial applications where bi-parting wood sliding doors require a secure, flush-closing latch at the center join. Typical installs include barn doors, room dividers, and closet configurations using two sliding panels that meet in the middle. The adjustable hook allows for fine-tuning the hold force to compensate for minor door panel alignment variation, making it practical for field installation on doors that may shift seasonally.
