The Nutron 2-bolt collar clamp might be small, but has incredible grip force. The design incorporates a threaded steel insert which means you can tighten the clamp till your heart’s content without the fear of stripping it. The clamp body has material removed strategically to save weight, but keep the high clamp force. The total weight is just 70g.
The Helmeri Pirinen clamp is built like the District Triple light clamps, but the graphic are taking inspiration from ancient Viking shields, the Helmeri Shield clamp fits perfectly in the Helmeri promodel collection.
Steel inserts are placed in the holes for the bolts, so the steel bolts won’t be able to strip the thread of the clamp. This extends the lifespan of the clamp.
