Standard Strength
MPS offers standard strength silicone station posts. These station posts meet the mechanical heights and comparable electrical performance of their porcelain TR numbers. This means they can be used as direct replacements in most cases. These weigh about 1/3 the weight of porcelain and offer excellent hydrophobic properties.
