These work for the Worx trimmer WG928
Size: 16 Line Spools+4 Caps, Size: 16 Line Spools+4 Caps
Recently purchased the Work String trimmer and blower bundle. I found these and ordered them in hopes they were the right ones. They fit and work perfectly. Super easy to install. Pop out the old one and pop in the new. The string is pretty durable and thick. I love the idea of pre loaded spools. It got so annoying having to rewind the string on the spool every time I ran out. Price is fair and worth it. Highly recommend these if you have the same trimmer.

Works like original equipment
Size: 16 Line Spools+4 Caps
Seems to handle the same work load as the manufacturer part. Good quality fit and design. No problems installing the string on the trimmer head. Definitely worth the purchase.
