When the listed entry matches
A standard inquiry identifies one product family and a published size or model. Include a link to the product page, the quantity and the intended application. Attach your installation drawing if fit still needs review.
A listed entry is a product reference, not a statement of stock availability or an approval for your assembly. Ask about any purchasing or technical detail that is not shown on the page.
When you need a change
Start with the closest reference and label the requested difference: overall length, a pin detail, a profile feature or another dimension. Keep the original reference visible alongside the requested value so the reviewer can see what changed.
HINGETRA lists customization for seven families: round, pin, gasket, grease-nipple, adjustable, square and flag. The exact change still needs Requirement / Specification Confirmation. Do not assume that a change offered for one family is available across every other family.
Catalog-backed customization families
These seven families have explicit product customization wording on their catalog source pages. Exact feasibility remains subject to requirement review.

Put fixed requirements and open questions on one drawing
- Closest product reference and the feature you want to change.
- Required dimensions and units, with measurement positions marked.
- Drawing number and revision.
- A view of the installation when surrounding parts affect the design.
- Quantity and destination.
- Any dimensions or details that remain open for discussion.
If a dimension must stay fixed to fit an existing assembly, label it. If you are open to a supplier suggestion, say which part of the design can change. This avoids spending time reviewing an option that cannot fit the frame or door.
Record what has been agreed
Comparison table Scroll horizontally →
| Item | Listed entry | Requested change |
|---|---|---|
| Reference | Family and exact model or size | Closest entry plus buyer drawing |
| Dimensions | Published values | Requested values clearly marked |
| Files | Installation drawing where needed | Current drawing revision with changed features |
| Next step | Confirm the entry and order requirements | Requirement / Specification Confirmation |
Keep the reviewed drawing revision with the quotation. If a dimension changes later, identify the revision and the affected feature in the next message. Do not leave two competing drawings attached without saying which is current.
Avoid three common gaps
First, a photograph does not define dimensions. Add a sketch or marked measurements. Second, “same as last time” needs a drawing or order reference. Third, a proposed change needs an explicit answer before it can be treated as agreed.
The drawing and dimension checklist includes an inquiry outline. Use the size guide when the question concerns a model number, compound size string or missing unit.
