Trampoline Enclosure Pole Blanking Caps (30mm Internal Diameter - Pack of 6)

Heavy-Duty Outdoor Protection to Prevent Internal Tube Rust & Enclosure Net Damage

Open metal trampoline enclosure poles collect rainwater, debris, and fallen leaves. Over time, trapped water rots steel poles from the inside out, while sharp, exposed metal tube edges snag, fray, and tear expensive safety enclosure nets.

Designed and manufactured in the UK by an engineer with over 30 years of precision CAD and tooling experience, these 30mm internal diameter pole blanking caps deliver a tight, weather-sealed friction fit. 3D-printed in UV-stabilized, high-impact PETG polymer, they cap off exposed tube ends cleanly to protect your trampoline frame and safety net through all seasons.

Key Outdoor Engineering Features & Safety Benefits

• Precision 30mm Friction Fit: Engineered to press-fit snugly into hollow enclosure poles with a 30mm internal diameter—staying firmly in place even during heavy winds and vigorous bouncing.

• 100% Weatherproof Marine-Grade PETG: Printed using tough, UV-stabilized PETG polymer. Unlike cheap stock plastics that degrade, fade, and snap in sunlight, PETG remains impact-resistant and flexible in frost or summer heat.

• Protects Netting & Steel Frames: Seals off sharp steel tube edges to prevent net tears while keeping rainwater out of the frame—stopping internal rust and premature pole failure.

• Custom Diameters Made to Order: Need caps for 25mm, 28mm, 32mm, 35mm, or non-standard tube sizes? Custom diameter caps can be custom-modeled to your exact millimeter specifications.

• Pack of 6 for Full Enclosure Coverage: Supplied in a cost-effective 6-piece set to replace all main enclosure pole caps across standard home trampolines.
