🔌 Which Cable Will Fit? (Quick Guide)

The door opening is sized for standard USB-C cables up to ~4.6 mm in diameter – this covers the vast majority of USB-C cables, including:

• ✅ The original DJI USB-C cable (what this door was designed around)
• ✅ Most standard USB-C charging and data cables
• ✅ Slim right-angle USB-C cables
• ⚠️ Thick braided or oversized cables may not fit – check your cable's diameter if unsure

Not sure? A standard USB-C cable is typically 3.5–4.5 mm. If your cable feels noticeably thick or stiff, measure it before ordering.

🧱 Materials – What's Made From What?

• Door (all variants): Printed in rigid PETG – durable, heat-resistant, and holds its shape under vibration and outdoor conditions
• TPU Plug: Flexible rubber-like material – compresses slightly for a snug, rattle-free seal
• Hard Plastic Plug: Rigid PETG – firm fit, easy to pop in and out cleanly

Both plug types are included in every variant. Extra plug packs add more of both types.

📦 Plug Pack Options – Which Should You Choose?

• Standard (2 plugs): 1x TPU + 1x Hard Plastic. Perfect if you're just getting started or only use one camera. Use whichever plug style you prefer and keep the other as a spare.
• +4 Extra Plugs (6 total): Ideal if you run multiple cameras, share gear with a team, or just want peace of mind. Small plugs are easy to lose in the field – extras mean you're never stuck with an open port.
• +6 Extra Plugs (8 total): Best value for multi-camera setups, race teams, or anyone who wants a full season's worth of spares. Stock up once and forget about it.

🎥 Great For:

• Live motorsport streaming
• Long recordings and time-lapse sessions
• Kayaking, biking, fishing, and outdoor filming
• Keeping the port sealed between shoots

📦 What's Included:

• 1x Pass-Through USB Cable Door (PETG)

• + Additional plugs depending on chosen pack

Frequently asked questions

What's the difference between this and the standard Action 4 & 5 door?

Weather-resistant against dust and splashes while a cable or plug is fully inserted. Not rated for submersion or heavy rain.

How long does shipping take?
Orders ship from Denmark within 1–2 business days. EU delivery typically takes 3–5 business days, worldwide 5–14 business days via PostNord.
