However, it's worth noting that the maintenance of wrought iron railings requires some effort. Regular cleaning, painting, or rust-proofing treatments are necessary to keep them in optimal condition. Despite this, the enduring beauty and durability they provide make the upkeep worthwhile.

If you’ve determined that the rollers need to be replaced, locate the screws that hold them in place. Use the appropriate screwdriver to remove these screws and take out the damaged rollers. Insert the new rollers in the same position, securing them with screws. Ensure they are appropriately aligned and able to move freely without obstruction.
