Product Description:  Heavy Duty Pile Cage Wheels, or circular spacers as they are also known, are designed to provide correct concrete cover to pile cage reinforcement bars. They are particularly suited to Raked Pile application where concrete spacers may have been previously used. These Heavy Duty Pile Cage Wheels can be attached as the pile cage is lowered into the ground. Their performance as an accurate guide is maximised by their ‘Push Fit’ and ‘Security Clip’ secure fixing mechanisms.
