- Aesthetic options: Caps and finishes offer weatherproof coatings and paintable surfaces to match or accent your deck design.
- Local regulations: For railings and cable systems, verify compliance with local code requirements and spacing rules before installation.
- Maintenance: Look for coatings that resist UV exposure and corrosion to reduce upkeep over years of outdoor use.
