TR7 wiper blades are correctly (UKRHD) 16 inch NS and 18 inch OS [pantograph arm). I believe that current suppliers hand out only similar blades of the same 16 inch size which is incorrect. The pin connection to the blade itself is fused (not removable), but most aftermarket blades now rely on removable pins. This can cause a problem on the TR7 since any play in the pin can cause the pantograph arm blade to come detached from its housing, thereby scratching the screen!
If you can, get hold of an original set of blades since it is still possible to replace the rubber elements using accessory shop rubber refills that are cut exactly to size. Indistinguishable from original equipment. Bit fiddly to fit but why replace the whole blade with an incorrect part?
