- Installation ease: Look for sleeves with simple wrap systems, Velcro or buckles, and minimal tools required.
- Length and coverage: Ensure the sleeve length covers the entire run or can be extended to prevent gaps.
- Safety and maintenance: Foil-backed or water-resistant sleeves reduce risk of mold and simplify cleaning.
