I was needing a new operator head unit for an automatic door closer for my garage as previous one had developed a terminal fault. Doorweb was the cheapest option I found. I contacted them first to make sure that this new unit would be a direct replacement for my now 'no longer available' unit. I got the confirmation and new unit (and rail) arrived promptly. I actually wasn't expecting or needing the new rail but it's handy to have a spare, just in case. Fitted the new head unit (genuine equipment) and door is back working properly. Delighted with the service and communication from Doorweb and would have no hesitation in recommending them or using them again. Thanks
