Barrier Standard Spigots are a very cost effective way of creating a glass balustrade with minimum intrusion visually. One major plus point to our hardware is the fact that it is made from 2205 stainless steel. This is far superior to standard marine grade 316 and 316L and has been developed over the last 10-20 years. For instance 2205 is commonly used for marine propeller shafts and achieves almost twice the corrosion resistance to ordinary 316. This makes the hardware perfect for coastal locations.
