What Suspends Tubular Chimes in Kieninger HTU?

How Are the Tubular Chimes Suspended in the Kieninger HTU Movement?

The Kieninger HTU is one of the most prestigious mechanical clock movements available for tubular bell grandfather clocks. Built by German experts in horology, this movement delivers deep, resonant chimes using long, tuned tubes—known as tubular bells. These tubular chimes must hang perfectly to resonate correctly. One of the most common questions we hear at Clockworks.com is: “What material suspends the tubular chimes in the Kieninger HTU clock movement?”

Let’s get into the details—what the material is, why it matters, and where to buy it.

What Is the Kieninger HTU Clock Movement?

The [Kieninger HTU Tubular Bell Clock Movement]() is a high-end mechanical movement built for precision timekeeping and superior sound. It features an 8-day triple chime function (Westminster, St. Michael, and Whittington), along with a cable-driven gear train and automatic night shut-off.

This movement powers large, heavy tubular bells, which produce rich tones far beyond traditional chime rods. It’s ideal for tall case grandfather clocks with enough depth to accommodate the length and swing of the tubes.

If you’re looking for one of the finest tubular bell movements in existence, the HTU is the choice. And you can buy it directly from Clockworks here: Kieninger HTU Tubular Bell Movement

What Material Holds the Tubular Chimes in Place?

The tubular chimes in the Kieninger HTU clock movement are suspended using Nylon cord. These wires run through holes drilled near the top of each chime tube and then connect to a chime block or hanger frame, typically made of metal.

These brass suspension wires aren’t just decorative—they serve a critical function:

• They isolate the chimes from the clock case, allowing each tube to vibrate freely.
• They provide durability, holding up under the weight of the long, resonant tubes.
• They help center the tone, by suspending the chime exactly at the acoustic nodal point.

The choice of cord ensures strength while minimizing vibration transfer that could deaden the sound.

Why Does the Suspension Material Matter?

Suspending the chimes with the right material in the right spot maximizes the acoustic resonance. When done correctly:

• The tubes ring longer and louder.
• The strike tones stay crisp and clean.
• The HTU movement maintains its full musical potential.

Can I Upgrade My Existing Clock to Use the HTU?

Yes, but keep in mind the HTU requires enough vertical space for the long tubular bells. Your clock case should be tall and deep enough to house both the movement and chimes. You also need a proper chime block to hang the tubular bells with brass wires.

Clockworks offers [complete HTU kits]() that include the movement, pendulum, chimes, suspension wires, and mounting hardware. This is the easiest way to upgrade or restore a high-end grandfather clock.

Final Thoughts

To set the moon dial on your Westminster Grandmother Clock Kit, rotate the dial clockwise until the correct moon phase aligns with the center of the arch. It’s best to make adjustments during a full moon for the most accurate results. Once set, the dial will automatically track the lunar cycle as long as the clock runs continuously.
