Dometic SK4 Service Hatch 700x405

A 700 x 405 mm Dometic SK4 exterior service hatch for caravans and motorhomes, giving flush, lockable access to a mid-sized storage locker or service point.

Why This Product

The SK4 is Dometic's standard flush-fit service hatch, moulded from weatherproof ASA plastic so it can sit permanently in an exterior wall. At 700 x 405 mm it sits between the range's smaller and largest sizes. It clips into a correctly sized cut-out without screws and closes with its own integrated multi-point lock, making it a straightforward like-for-like swap once the opening size is confirmed.

Key Features

• Moulded from weatherproof ASA plastic
• Clips into the cut-out without screws, for a clean flush fit
• Can be mounted horizontally or vertically
• Closes with an integrated multi-point locking system, operated by key
• Made to the 700 x 405 mm SK4 opening size

Ideal For

• Replacing a cracked, sun-damaged or broken 700 x 405 mm SK4 hatch
• Adding a new lockable service point during a caravan or motorhome rebuild
• Restoring keyed security to a storage locker or compartment
• Matching existing SK4 hardware elsewhere on the same vehicle

Optional Fitment / Upgrade Notes

This hatch is sold as a direct opening-for-opening replacement, so your existing cut-out must match 700 x 405 mm exactly. Dometic lists a compatible wall thickness of 23-42 mm for this size, so check your panel falls within that range, and make sure the cut-out edge is clean and flat so the moulded frame seats and seals properly.

FAQ

Will this fit my existing hatch opening?
Only if your current cut-out measures 700 x 405 mm exactly — this is a direct size-for-size replacement, not an adjustable hatch, so measure first or contact us to confirm.

Do I need to drill or use screws to fit it?
No. It clips into a correctly sized cut-out without screws, and can be mounted horizontally or vertically.

Does it come with a key?
Yes — the integrated multi-point lock is supplied complete with its key.
