NEXT time you're queueing for a burger look up at the ceiling and you may spot a Haslingden firm's product.

Air grilles made by ducting specialists Caswell Engineering's sister firm Konvekta are used in McDonald's restaurants around the country and the firm has recently completed a contract at a fast food site at Liverpool FC.

The firm, based on the Knowsley Road Industrial Estate, employs more than 40 people manufacturing ventilation ductwork and providing a plasma profiling service.

Together with Konvekta, which manufactures air grilles, louvres and air handling units, the firm has seen turnover almost double in the past five years.

The order book for 1996-97 now stands at £1.7 million and the firm is planning an extension to its factory site and recruitment of more than 10 new staff to cope with the extra work.
