Shacklock was a pioneer in the manufacturing of coal ranges. The Orion range was the main line produced and, by 1894, the company's appliances were being sold throughout New Zealand. The limited liability company of H.E. Shacklock Ltd was formed in 1900 with a capital value of 25,000 pounds. For as long as coal remained the main source of energy, H.E. Shacklock was the market leader in producing solid fuel ranges and heaters.
