The Greenough 4-C is one of the most classic, fundamental single fin designs for a longboard…ever! 

The man behind this revolutionary fin is George Greenough, whom the surf world is forever indebted to for his wave-riding performance innovations beginning in the 60’s. Greenough paved the way from traditional logging to more progressive surfing in the pocket through the development of his Velo-Spoon kneeboard designs. To complement his kneeboards, Greenough found inspiration from mother nature for his fin templates through studying the tail fins of tuna–one of the fastest and most maneuverable fish in the ocean. The subsequent high-aspect ratio design he created allowed surfers to place themselves in more critical parts of the wave and execute more radical turns; and it ultimately ushered in a new era of high performance capability.

The 4-C is a direct descendant of Greenough’s “Stage 4” tuna fin-inspired designs from the early ‘70s; this iteration was conceived earlier on in the evolution of the Greenough and True Ames collaboration that ultimately led to the 4-A. The 4-C template represents the first step taken in the move away from a traditional pivot fin. Greenough kept the upright nature and minimal rake of a pivot fin, but shaved off a considerable amount of surface area in pursuit of a more high-aspect ratio design. This translates to a higher performance fin that is even more maneuverable, and faster down the line with less drag.

  • Unique design: semi-pivot template but with less area 
  • Works great on all types of longboards 
  • Solid fiberglass construction, flat matte finish

bought these after another set of floating shelves didn't work. these are great and an awesome value!! i've used these in my guest bathroom and also throughout my house. they look great everywhere and are much easier to hang compared to others. my husband was hesitant after the last shelves but these turned out amazing. they are very sturdy and hold a good amount of weight. i would recommend buying these compared to any others.

Great Wall Shelves – Sturdy, Easy to Install, and a Fantastic Value!
Size: 4 pcs: 15.7*5.7, Color: White
I’m really happy with these wall shelves! They’re sturdy, well-built, and hold up perfectly under weight—no concerns about them sagging or bending. The installation was super simple, and everything was clearly labeled with no missing parts, which made the whole process smooth and stress-free. I love that they come in a set of four, making them perfect for displaying books, plants, or decorative items in multiple spots around the room. The design is sleek and minimal, so they fit in with pretty much any style of decor. Overall, these shelves are a great value, and I would definitely purchase them again. Highly recommend if you’re looking for reliable and easy-to-install shelving!
