How can I check the condition of my turning fittings and when should they be replaced?

The condition of your pivot hardware can be checked at regular intervals or when you notice unusual behavior such as squeaking, sticking, or difficulty turning. Here are some steps that can help:

• Visual inspection: Check the pivot hardware for visible damage such as rust, wear, or deformation. Also look for loose parts or missing components.
• Function test: Test the pivot hardware by opening and closing the door or window. If it does not move smoothly or makes unusual noises, this could be a sign of a problem.
• Lubrication: A lack of lubrication can lead to wear and premature failure of the pivot hardware. Use suitable lubricants to keep the pivot hardware moving smoothly.

If your pivot hardware is still causing problems despite regular maintenance and care, it may be time to replace it. If you see cracks, broken components, or heavy rust, these are dangerous signs that immediate replacement is necessary. Likewise, if the pivot hardware still sticks or squeaks despite lubrication, you should consider replacing it.
