About our RDM Extensions
Heavy Duty. Light Weight.
We beefed-up our tough line of mast extensions. Take your choice from a winning line of Carbon and Aluminium mast extensions, including Heavy Duty (HD) and PRO and PRO Stainless versions for super-efficient load distribution. All extensions are universal pin compatible except the Aluminium US-System and feature large diameter pulleys for slick downhauling power.
