Roll-up door latches and storage door hasps
This is the family where a millimetre of mounting-hole pattern decides whether the part fits. It is also the family that keeps a roll-up door working after the original hardware has been discontinued.

Four decisions shape this order. Pick what applies and we will confirm the rest with a sample.

No model references, prices, stock levels or sales figures are published here. Where a parameter depends on the specific model, we confirm it for the model you order rather than describing the whole family.
Fit and compatibility
- Send the door type and mounting dimensions, or a photo of the existing latch — that is usually enough to identify a match.
- Where the original part is discontinued, we work from the drawing or reverse-measure a sample you send.
- The mounting-hole pattern is verified with a First Article Inspection before the full run — this is where a latch fails to fit.
- Latches and hasps are frequently ordered with overlock hardware; both are verified against the same sample door.
Fit confirmed by sample, not by drawing. Send a door photo, the cylinder size or the mounting dimensions and we will send a physical sample before you commit to a quantity.
Ordering information
The commercial terms for this family. They are confirmed with the quotation, so a re-order two years from now carries the same conditions rather than a new set.
- MOQ
- From 500 pcs
Heavy customization — a new mold, a special key system, printed blister cards — may require more. The exact figure is confirmed with your quotation. - Samples
- From 5 days
Sent so you can check fit and finish on your own door before committing to a quantity. - Batch production
- Around 30 days after spec and artwork confirmation
Peak periods such as Chinese New Year are flagged when you order. - Delivery terms
- EXW · FOB · CIF · CFR · DDP
More than one term can be quoted so you can compare what the goods cost against what the freight and duties cost. - Payment
- T/T · L/C · Credit card
A first order normally runs on a deposit with the balance against the documents or on shipment. - Documentation
- Spec sheet, inspection record, packing list, pre-shipment photos
Test records are issued per model and per finish, and are available for the model you order.
Tell us the quantity, the door type and the destination country and we will quote the configuration rather than a list price.

Buyer questions
How do I match a discontinued latch?
Send a photo of the existing part with a ruler, or post us a sample. We reverse-measure it and confirm the replacement against the dimensions before production.
Do you supply complete assemblies or just parts?
Both. Complete latch and hasp assemblies for a new installation, or replacement parts and kits — bolts, springs, mounting plates — for maintenance. Tell us which, because the packing and MOQ differ.
Can you work from the door manufacturer's drawing?
Yes, and it is the most reliable input. Send the drawing or the door model and we will confirm the mounting pattern and fastener positions.
Will the latch fit a door we already have?
We verify the hole pattern with a First Article Inspection against your drawing or sample before the full run. If the first article does not fit, the batch does not start.
What makes a latch fail before the door does?
Usually the hasp or the mounting rather than the latch itself, and often a door that has drifted out of alignment. Working through the door before replacing the part is what prevents the same failure a second time.
Are the fixing bolts supplied with the assembly?
Tell us the door thickness and the fixing arrangement and we will confirm what travels with the assembly. Fixings can be included or left out to suit how your installers work.
