JACK CYLINDERS

Callcott & Downey are able to manufacture a large range of jacking cylinders built to your specifications. Our aim is to manufacture cylinders to such a high standard, that they actually save you money by returning a significantly extended service life. We achieve this by re-engineering design flaws and by utilising the most suitable and durable materials for the job at hand.
