What we built
A stationary distributor designed for real winters.
Three principles guided every decision — coverage consistency, user safety, and material efficiency.
Even Coverage
Curved fins distribute salt in a controlled arc, reducing bare patches and over-application.
Less Waste
Controlled feed releases only the salt needed, reducing runoff to lawns and drains.
Freestanding Design
Sits at the edge of a driveway or porch. No permanent installation required.
