What device must be installed to limit the movement of commercial cooking appliances?

The correct answer is a restraining device, as it specifically serves to limit the movement of commercial cooking appliances, ensuring they remain stable and secure during operation. This is vital for safety, as cooking appliances are often subjected to vibrations, heat, and movement, which can lead to hazardous situations if not properly secured.

A restraining device typically consists of components that connect the appliance to a wall or floor, preventing it from tipping over or sliding during use. This is particularly important in professional kitchen environments where the risk of spills or accidents can pose significant safety hazards. The device helps to enhance overall operational safety and can be a crucial element in meeting local codes and regulations related to equipment safety in commercial kitchens.

The other options, while related to securing equipment, do not specifically indicate a mechanism designed to limit movement in the same way. For example, an anchoring device generally refers to a broader category of fasteners used for stability but is not necessarily specific to limiting motion; a secure fixture typically denotes a stable installation but lacks the defined role of movement restriction; a stabilizing bracket may provide support but is not explicitly meant to address appliance movement on its own. Thus, the restraining device is the most accurate choice for this particular function.
