What Helps Us Quote Accurately

  • A photo of the door edge or the existing lock body
  • Door thickness and backset in millimetres
  • Whether the app must unlock actively or by request
  • Packaging and branding requirements
  • Destination port or forwarder warehouse

Missing information is fine. We will quote what we can and list what is still open rather than assume a value.

PDF, JPG, PNG or DWG. A photo of the door edge with a ruler is usually enough to confirm the fit.

We reply within 12 working hours. Send a door drawing or a photo of your existing lock body and we will confirm the fit before production. File attachments up to 10 MB; if the upload does not go through, email the file to mike@bbdhome.com and quote your company name.

Before You Send It

Four things worth knowing before you fill the form in.

Swipe the table sideways to see the full specification →

Before you send
Do not know the mortise size?Send a photo of the door edge with a ruler against it. We read the body from the photograph.
Want a sample first?Say so in the message. Samples ship in 3-7 days and the cost is refundable against the first bulk order.
Is the quote itemised?Yes. Unit price, MOQ, sample cost, tooling where it applies, and lead time are separate lines.
What if something is still open?It is listed on the quotation as an open question rather than quietly assumed.
File attachmentsPDF, JPG, PNG, DWG, DXF and STEP, up to 10 MB. Email the file if the upload fails.

What Happens After You Send It

  1. We read the requirement

    If something is ambiguous we ask before quoting, rather than quoting two versions.

  2. We match the model

    Model, unlock combination, app version, mortise or body and packaging scope.

  3. We issue the quote

    Unit price, MOQ, sample cost, lead time, trade term and the documents we will issue.

  4. Sample and approval

    For a new specification or a private-label order, the sample and the packaging proof are approved in writing first.
