Dr. Shrink DS-SUPERCAP XL Super Cap Shrink Wrap Support Pole End Cap

The Dr. Shrink DS-SUPERCAP Extra Large End Cap is a purpose-built support accessory designed to protect and stabilize shrink wrap covering systems on boats, RVs, and powersports equipment. This black plastic end cap fits securely over the top of standard 2x4 lumber boards commonly used as vertical support poles beneath shrink wrap covers, helping to prevent punctures and tears in the wrap film by creating a smooth, rounded contact point.

Key Features:

• Extra Large (XL) size — designed to fit snugly over the end of a standard 2x4 board
• Prevents shrink wrap punctures — cushions and protects the wrap film from sharp lumber edges
• Black color — UV-stable finish suitable for outdoor use
• Compatible with standard shrink wrap support pole systems — works with 2x4 framing commonly used in boat and RV winterization
• Single cap included per unit
• Durable plastic construction for season-after-season reuse

The DS-SUPERCAP is an essential component for a professional-quality shrink wrap installation. By capping the top of your support poles, you protect your shrink wrap investment from premature failure caused by contact with raw lumber ends, ensuring a tight, long-lasting cover throughout the storage season.
