Please note that there are two designs of clips fitted to the DC41 and DC43 models as Dyson revised them halfway through production, but this is the latest model's design, which fits all of the DC41 & DC43 models, If you have an older machine with the earlier design; you must swap both parts which requires a some knowledge & experience as it is not an easy task, we recommend you seek professional advice for fitting if you do not feel confident to do it yourself
