- Weather Resistance: Look for anti-corrosion coatings or UV-resistant materials to withstand elements, especially if installed outdoors.
- Installation Ease: Sleeves should come with clear installation instructions or kits including accessories to simplify the process.
- Additional Features: Some sleeves include air filters to purify intake air or decorative caps to protect and conceal. Consider these options based on your needs.
- Protection & Insulation: The sleeve acts as an insulator and provides a sealed passage for cables and tubing, preventing energy loss or pest intrusion.
