Model: F-1645
Type: Under-Center Draw Latch | Size: Medium | Material: Steel, Electric Galvanized | Mount: Exposed
Product Description
The F-1645 is a medium-size under-center draw latch designed for applications where a secure, vibration-resistant connection is needed between two panels or surfaces. The under-center design is what makes this style of latch stand out — as the latch closes, it passes through center and locks itself in place, which means vibration and shock won’t cause it to rattle open on its own.
One of the more practical features of this latch is its tolerance for misalignment. The latch and keeper don’t need to sit perfectly flush or coplanar to engage properly, which takes some of the pressure off during installation and gives you more flexibility when working with enclosures or panels that shift slightly over time or under load.
The adjustable grip lets you dial in the clamping force to suit your specific application — tighter for a more secure seal against a gasket, or slightly looser where repeated access is needed throughout the day. This makes the F-1645 a flexible choice across a range of use cases without needing to stock multiple different latch models.
Built from steel with an electric galvanized finish, it’s solid, corrosion-resistant, and ready for both indoor and outdoor use. The exposed mounting style means straightforward installation with visible hardware — no recessed cutouts needed.

How It Works
The under-center mechanism works by pulling the latch handle past the center point of its arc as it closes. Once it passes center, the geometry of the latch holds it firmly in the closed position — even under vibration, shock, or repeated movement. To open it, you simply lift the handle back through center. It’s a proven mechanical principle that doesn’t rely on springs or secondary locking mechanisms to stay shut.
