When your wipers are applying uneven pressure, jumping across the windscreen, or becoming noisy; you may want to upgrade the blade assembly. Tridon wiper blades range in size from 13, to 26 inches long – for both front and back windows. Their low profile design uses a galvanised zinc steel frame - with stainless steel rivets. This ensures maximum corrosion protection. Plastic bushes keeps your wipers smooth and quiet - with a long service life. Each Tridon standard blade wiper blade is fitted with a quality rubber refill - and supplied with adaptors to suit various arm designs.
