Buying Guide: Key Purchase Considerations
- Post size compatibility: measure post diameter and height to match finial diameter and screw length.
- Material choice: cedar offers outdoor durability; poplar or pine-finish options suit indoor decor but may need sealing.
- Style compatibility: choose round ball for modern/soft lines or Gothic/post-cap styles for rustic or period looks.
- Installation ease: pre-installed screws simplify mounting; check screw length relative to post thickness.
- Quantity needs: purchase sets that cover all posts in a project to maintain uniformity and reduce ordering complexity.
