Eye and Block Risers

This colorful riser is custom engineered to fit the Ronstan RF20171 Single Upright Lead Block perfectly, lifting it slightly off the deck, spar or other location to provide 8mm of extra clearance. Check the 16mm version for a bit more clearance. It comes in 6 available colors to match or offset hull color, or to color code your leads, such as red to port and green to starboard. Can be installed directly side by side, just like the RF20171 Lead Blocks, where color coding becomes especially useful. Made of glass-reinforced polymer they have high compressive strength, excellent abrasion resistance and outstanding shock resistance. Install like other marine hardware, with bedding compound and stainless steel bolts or screws (not supplied). Built-in indexing nubs help position the block when installing. Coordinates with our other risers, our line beads and Color Cleats™, too.
