What makes Harmony Hollow chimes so good...

How the brass is prepared and mounted, and the cording.

Brass:

• At the nodal points (the area of a vibrating tube where there is no vibration) the suspension holes are drilled into the tubes and rods. This results in the cords not dampening the sounds and the tubes don't slowly eat into the cord.
• All Harmony Hollow chime tubes and rods are deburred, removing any sharp edges where the cord passes through the tube.

Cord:

• Besides the deburring of the tubes and rods which protect the cord, many other cord protection measures are taken.
• Harmony Hollow Chimes uses non-slip knots, and then weld the knots together with a hot knife.
• All chime cord is specially custom-made for Harmony Hollow consisting of an inert polypropylene that is totally resistant to mold, mildew, or rot.
• The cord is not affected by acids, including acid rain.
• To prevent cracking from sunlight, just the right amount of ultraviolet inhibitor is used in the cord.
• For abrasion resistance, there's also a strengthened core with a tightly woven outer sheath.
   

With the many precautions Harmony Hollow Chimes takes, the cord becomes virtually indestructible.

The same company that makes cord for Harmony Hollow Chimes makes the same type of cord used by the US Coast Guard for their life preservers and life rafts. Slightly different cord diameters and Harmony Hollow's better abrasion resistance are the only differences.
