Rocksolid guarantee

Shop with confidence. If it’s not working out, you can return it (consumables, electronics, undergarments and swimwear excluded).
Really. If it's not up to snuff after you use it (a couple times) you can still bring it back. It lasts longer than 30 days, but not forever. We'll be fair about it.


Time-tested stoppers with a transverse taper that allows you to place them securely in bottlenecks, flares, and shallow seams. The tapered shape extends versatility and adds multiple placement options. In addition, the classic shape (convex on one side, concave on the other) allows the unit to cam into position when loaded.

  • Made of 6061-T6 aluminum with a galvanized steel cable
