Which YEN Concealed Product Lists a Lifetime Spring Guarantee?
2026-10-25
YEN lists a lifetime guarantee on the spring in its Concealed model in the Designer Door Springs range, which suits doors up to 40 kg. Retailers can use that specific product feature when discussing a purchase, while asking YEN to confirm the applicable written terms. The separate Concealed hydraulic door closer is a different product. Its shared name does not carry the spring model's guarantee across to it.
Which Concealed product should you show a customer asking about the guarantee?
Show the Concealed designer door spring. Its catalogue features include S.S. 304 fore-end plates, a painted body, adjustable spring strength and a spring with a lifetime guarantee. The product is described as invisible when the door is closed and suitable for doors up to 40 kg.

View the full Designer Door Closers range →That gives a retailer a concrete product story: concealed appearance, a stated door-weight limit and a guarantee statement tied to the spring. Discuss those features together so the customer can consider both appearance and suitability before buying.
Use the full category and model name in the sales conversation. A request for a "YEN Concealed" alone leaves two different closing products in the discussion.
How is the Concealed hydraulic closer different?
The Concealed model in Designer Door Closers lists a 100 kg door weight capacity, double speed control, special oil seals and a heavy gauge long arm. Those specifications belong to the hydraulic closer, rather than the 40 kg designer door spring.
| Sales question | Concealed designer door spring | Concealed hydraulic door closer |
|---|---|---|
| Which range contains it? | Designer Door Springs | Designer Door Closers |
| What door weight is listed? | Doors up to 40 kg | 100 kg capacity |
| Which operating feature can you explain? | Adjustable spring strength | Double speed control |
| Where does the lifetime spring guarantee appear? | In this model's spring feature description | This model's catalogue entry does not list that guarantee |
Match the recommendation to the customer's door and desired closing behaviour. If the customer wants controlled closing speed, discuss the hydraulic model's listed controls and ask for suitability confirmation. If the customer is interested in the concealed spring and its guarantee statement, keep the enquiry attached to that specific spring product.
What can a retailer say about the lifetime spring guarantee?
A clear explanation is:
YEN's Concealed designer door spring lists a lifetime guarantee on its spring and suitability for doors up to 40 kg. We can ask YEN to confirm the written guarantee terms for this product and your purchase.

The published feature names the spring. It does not set out cover for every component, labour, removal and refitting costs, or an automatic replacement arrangement. Ask which of those, if any, are included before making them part of a sales offer.
Likewise, ask how the applicable terms define "lifetime", what conditions or exclusions apply, and who handles a claim. These are questions for the supplier, not additional promises established by the catalogue description. YEN's website terms distinguish site information from the applicable product warranty terms agreed at the time of sale.
Can the guarantee decide which product you recommend?
Start with the door's requirements. The Concealed designer spring's listed 40 kg suitability and the hydraulic closer's listed 100 kg capacity are different product facts. A guarantee statement does not establish that either model fits the customer's door construction or installation space.
For a customer choosing the designer spring, explain its concealed appearance and adjustable spring strength, then ask for fitting guidance for the actual door. For a hydraulic closer enquiry, explain the relevant closer features. Keep the guarantee wording with the model to which it belongs.
This also gives your shop a useful way to present the products: show the correct model, explain its published features and offer to resolve the remaining purchase questions directly with YEN.
How can you get a model-specific answer before the sale?
Use the YEN product enquiry page to ask about Designer Door Springs, Concealed, its lifetime spring guarantee and suitability for the proposed door. Include the door weight and construction so the discussion addresses the intended application as well as the guarantee terms.
If you are considering stocking the product, use the dealer enquiry page to discuss the Concealed designer spring, current trade pricing and the product information your sales team needs. A focused enquiry gives you a clearer basis for presenting this particular YEN product to your customers.
