"Helix or Helical: Are These the Same YEN Door Spring?"

Use those shapes to identify which listing to discuss. A photograph can help distinguish the models, but it does not confirm that a new spring will fit the existing fixing positions.

If a customer says only “the YEN spring,” show both listings before preparing the quotation. Write the selected name beside the category so the same identification reaches the person placing the order.

What does the catalog list for each model?

Detail	YEN Helix	YEN Helical
Category	Designer Door Springs	Door Springs
Body or construction description	M.S. body, meaning mild steel	Heavy gauge
Finish description	Powder-coated shades with chrome parts	Painted shades available
Listed size options	No size stated in the product listing	150mm standard and 100mm mini
Spring strength	Adjustable	Adjustable

Helical's listing also describes a strong closing action. It does not give a door weight rating. Helix's listing likewise gives no door weight rating or fitting dimensions. Keep those unanswered questions separate from the features that are actually published.

The Designer Door Springs range and Door Springs range provide the two catalog entries. Do not transfer Helical's size options onto a Helix quotation because the names sound alike.

Does adjustable spring strength make them interchangeable?

Both products list adjustable spring strength. That shared feature does not establish matching fixing positions, clearances or suitability for a particular door.

For a replacement enquiry, record the existing model if known, photographs of the spring and fixing area, and the door's material and dimensions. Include the actual door weight if available. Ask the supplier and installer to confirm the proposed model and fitting arrangement before promising a direct replacement.

If the customer wants controlled closing speed, record that requirement separately. Neither of these two product listings states hydraulic speed control. Adjustable spring strength alone should not be quoted as a promise of that feature.

What should a clear quotation say?

Use “YEN Designer Door Springs, Helix” or “YEN Door Springs, Helical” as the product identity. For Helical, add the selected standard 150mm or mini 100mm option after suitability has been confirmed. For Helix, request the current dimensions instead of borrowing a size from another model.

Record the confirmed finish separately. The listings describe finish types but do not name a complete shade selection for either model, so ask for the current options before promising a colour.

A Helix enquiry could read: “Please confirm YEN Designer Door Springs, Helix, for the door shown in the attached photographs. Please provide the current dimensions, finish options and fitting information before we finalise the order.”

What should the retailer check before handing over the spring?

Compare the supplied product with the confirmed category, model and finish, plus the selected size where applicable. If the item differs from the approved order, resolve the difference before presenting it as a substitute.

Give the customer the fitting and adjustment information for the confirmed model. Keeping Helix and Helical distinct from the first enquiry through handover makes the quotation clear without relying on a similar-sounding name.
