Innovation: Lock anchor wire gates with a tube

Emanuele Pellizzari who has been in the business for 20+ years and now also sells bolts and anchors have come up with an interesting innovation making anchors with wire carabiners safer. He simply puts a tube on it locking the gate. "Best case belay anchor should have two carabiners. A simple solution for single wire gate anchors, costing virtually nothing is to place a tube on the wire gate (cost 0,03 Euro). Pull it up, you "free" the locking system", pulling it down, you lock the gate (see picture). You only need to choose the right diameter, not too tight, not way too loose. For dummies (real dummies): If you pull the tube too early, you prevent the gate to close, lowering the strenght of the carabiner by 60%. First close the gate, then pull the tube down so it goes OVER the nose of the carabiner." Emanuele also says that a wire gate is normally better as normal gate anchor carabiners collect dust and in the end the gate will stiffen making it impossible to be completely closed. Further more, you can not look it with his suggested tube innovation.
