• Holds a solar cover (bubble blanket) on a large aluminum tube
\n
• Lets you roll the cover on/off the pool easily
\n
• Prevents damage from folding, dragging, or UV exposure
\n
• Reduces evaporation + keeps water warm by supporting the solar blanket

🧱 Build Quality

\n

Commercial reels are built very differently from cheap residential ones:

\n

\n
• Thick aluminum tubing (won’t sag over time)
\n
• Steel bearings for smooth cranking
\n
• Wide base for stability (prevents tipping into pool)
\n
• Corrosion-resistant coatings (important for chlorine environments)
\n
• Reinforced crank handles (often dual-side for large pools)

  \n
  \n
\n
• Keeps cover:\n
  \n
  • Clean
  \n
