Our expertise is focussed on the design and manufacture of high performance window wipers for the Marine Industries.There is no built in life expectancy in our marine window wipers, indeed they have been designed to last the lifetime of a vessel, crane etc. This is reflected in the 3-year Warranty we offer on our marine wipers to customers and for the special services of the MOD and the RNLI this is extended to a Lifetime Warranty.
