This cage routes and contains flexible lines cleanly, and secures them in a manner such that the flexible lines will not snag on loader treads, or other obstacles. The cage is formed by distinct placement of straight pins and angle pins in a flat bed. The support holder may be used independently, or in sets, to contain ⅜″, ½″, and ¾″ flexible line. Placement is accomplished by an operator placing the line past and over pins and then bending over a final angle pin to finally contain the line within the cage. The line remains contained until an operator extracts the line, when the process is reversed.
