Polyform G-2 Fender 4.5" x 15.5" — Black
A dependable mid-size fender for everyday docking. The Polyform G-2 is one of the most widely used fender sizes in recreational boating — sized right for powerboats and sailboats in the 20–30 ft range, and tough enough to handle repeated contact with docks, pilings, and other vessels.
Constructed from high-density polyethylene, the G-2 resists UV degradation, saltwater corrosion, and impact deformation. The ribbed surface provides grip and helps the fender stay in position against the hull. A through-hole at each end accepts standard 1/4" fender line for easy attachment to cleats, rails, or stanchions.
Key Features
- Size: 4.5" diameter x 15.5" length (G-2)
- Color: Black — low-visibility, clean look at the dock
- Material: High-density polyethylene — UV-resistant and impact-tough
- Ribbed surface for hull grip and position stability
- Through-hole ends accept standard 1/4" fender line
- Suitable for freshwater and saltwater use
Best Use Case
Best suited for powerboats and sailboats in the 20–30 ft range docking in marinas, alongside pilings, or in side-tie situations. The G-2 is a versatile all-around fender — use 3–4 per side for full hull coverage on most mid-size vessels. Works in both freshwater and saltwater environments. For larger vessels or higher-impact docking situations, step up to the G-3 (5.5" x 19") or G-4 (6.5" x 22").
Parts Desk Insights
The G-2 is the most common entry-level fender size and a reliable seller across all boat categories in the 20–30 ft range. Customers typically need 4–6 fenders to outfit both sides of the boat — always ask how many they need. Pair with the Polyform EFC-2 Fender Cover (Black) to protect the hull from scuff marks and rubber transfer. For fender lines, cross-sell the Sea-Dog Fender Line 1/4" x 6' Black, Blue, or Gold Braid. Customers wanting other colors should be directed to the G-2 Blue and G-2 White variants. For larger vessels, suggest the G-3 Black Fender 5.5" x 19" or G-4 Black Fender 6.5" x 22". For fender cleaning, recommend the Aqua-Tek Dinghy & Fender Cleaner 750ml.
