The slotted iron tubes have a length of 10'-0” (3.05 m), an exterior diameter
of 1.315” (33.4 mm) and a weight of 1.4 lb/foot (2.1 kg/meter). They are zinc
plated in order to resist corrosion effectively. The slot which has a width
of 0.25” (6.35 mm) will only let the pendants of the chain pass through.
The remaining parts of the chain are contained in the tube in order to protect
it from environments that are dusty, humid or that contain other forms of contaminants.
Weight: 1.4 lb/foot (2.1 kg/meter).
