FAQ
What size pendulum sticks is this nut compatible with?
The nut features a standard universal thread that fits the majority of wooden pendulum sticks used in traditional mechanical clocks.
Can the rating nut be adjusted while the clock is running?
Yes, the knurled adjustment allows fine tuning without stopping the clock, though for the most accurate results we recommend making small adjustments and observing the swing.
Is the brass material safe for antique clocks?
Absolutely. Brass is a historically appropriate material that will not react adversely with other clock components and adds a period‑correct appearance.
How do I install the nut on my pendulum?
Simply thread the nut onto the pendulum shaft until it seats securely, then use the knurled section to slide it to the desired position for timing adjustment.
What is the warranty on this product?
Retuios offers a one‑year limited warranty covering manufacturing defects and material failures.
