This masthead fits on a DM-2 anodized, aluminum teardrop-shaped mast extrusion with standard 2 1/4 in. (57mm) by 2 1/2 in. (64mm) perpendicular measurement diameters. This masthead casting is complete with two Nylon sheaves and clevis pins. It attaches with two SSP3 pop rivets.
Dwyer spars have and do supply many builders with spars and parts. We stock all of their most popular replacement parts. Note that DM-20 and DM-3 sections are used as mast only and DM-1 and DM-2 as both masts and booms.
