“I bought this product to replace the existing one which had been in position for 12 years. The replacement from Tradefit was an exact swap and therefore easy to fit. My one issue is that the adjustment screw has already become very difficult to turn but fortunately has stuck in the correct position. I'm sure that some WD40 will sort that out. I may order the WD40 from Tradefit (at no charge please!)”
