Online support
Ask before you order.
Tell us about the opening, product or existing order, and add a few photos. Photos are the quickest way for us to give you a sure answer. We reply by email.
What helps us most
- Photos: the whole opening from straight on, and a close-up of anything unusual
- Which product and how many openings
- Your measurements in millimetres
- Where the readings differ or a surface is missing
- Your town and any order reference
