Ray-Placeable Construction.
The Ray-Placeable vault lights are constructed from steel, concrete and a non-shaling glass set in a plastic compound with metal ring protection, spaced to give a maximum amount of light. The construction is the result of 20 years' experience and is featured (1) by being of sufficient strength to eliminate all vibration; (2) no metal exposed on the under surface to cause condensation; (3) a non-manganese, non-shaling glass set in a plastic compound with metal ring protection, preventing shaling from expansion and contraction; (4) most important, the glass can be replaced without chipping the cement, making the construction everlasting.
