Ronstan RF137
Set of Pre Owned vintage Ronstan RF137 adjustable mast spreaders (made in Australia), typically measuring around 16 inches.
While Ronstan manufactured these spreader brackets and kits as universal or multi-class hardware components rather than exclusively for a single specific production sailboat, they were widely used across several popular one-design dinghies, small keelboats, and trailer sailors from the 1970s through the 1990s—most notably classes like various small scows, day sailers, and classic lightweight racing dinghies utilizing small-section aluminum masts.
Manufacturer: Ronstan (Australia)
Part Number: RF137 (stamped directly into the stainless steel mast base/tang plate)
Length: 16 inches (adjustable pin/telescoping layout)
Design: Stamped stainless steel mast brackets with tubular aluminum spreader arms and end tips designed to capture and support the shrouds.
