Send the model or the application, the quantity and the market. If you have a door drawing or a photo of the existing lock, include it: that one attachment removes most of the back-and-forth.

Visit or Video Tour
If you would rather see the line before ordering, book a video factory tour. Bring your model questions and the team will walk the assembly and inspection area with you.
How a Visit Works
Most buyers start with a live video walkthrough rather than a flight, because it takes an hour and can focus on the model they are actually ordering. If the project size justifies a visit, we arrange it by appointment.
