3-Channel Heavy-Duty Yellow Jacket AMS System Center Section. The YELLOW JACKET 3-CHANNEL AMS (Advanced Modular System) is patented technology that utilizes separate cable protector sections and ramps to create a system that is fully expandable to hold an unlimited number of cables. By detaching the ramps, you can also quickly add cable runs and ADA compatible side ramps to existing systems. The Yellow Jacket AMS readily handles heavy truck and bus traffic while providing easy access for pedestrians, carts and wheelchairs. Hinged lids make for easy loading of cables and hoses.
