What is the maximum depth that Insta-Chains can be used?

The correct choice indicates that Insta-Chains can be effectively used at a maximum depth of 6 inches. This depth allows the chains to provide adequate traction and stability while also ensuring that the chain links can fully engage with the surface beneath the vehicle or equipment. Using Insta-Chains within this depth range maximizes their effectiveness in preventing slippage and enhances safety during operations in conditions such as snow or ice. Beyond this depth, the chains may not provide the same level of traction, which could lead to decreased operational efficiency and increased risk of accidents.
