The S-75-WA winch shaft adapter can be used with a line truck winch and an S-7500 or S-8500 Spider® reel to take up Spider rope instead of using a puller outfitted with a hydraulic Spider® rewind. The new Sherman+Reilly S-75-WA is manufactured out of steel and is CNC precision machined for a more precise fit. The newer version has less “slop and lope” when pulling in the Spiderflex rope than the older cast winch shaft adapter.
