Why do you only have two series of wipers?

We believe the wiper market has become cluttered with too many wipers and small differences between them. In our two series of wipers, we believe we have captured the requirements of most customers at an economical cost.

Do you produce custom or OEM wipers?

Yes, for volume orders we can manufacture wipers to nearly any specification. Please complete our custom wiper design form with your requirements for a quotation.

Can I get samples?
