Everything that the architect,
builder, or owner has wanted and demanded of sidewalk lights
is found in the 3-Way Armored Glass Construction.
3-Way Armored Glass Sidewalk Lights
embody all the results of our quarter-century of experience. It is
the proven construction, for installations ten years old are as
good today as when put in.
In this construction, the glass—both
square lenses and round lenses—is armored against both
expansion pressure and the assaults of traffic. Each lens is caulked
with tar and brimstone compound in a cast iron galvanized ring, or
bottomless cup. This is built right into the concrete slab, being
perfectly embedded with a permanent bond.
These slabs are made to fit the
sidewalk openings. Reinforcing is of approved types with great
strength and freedom of vibration. To install, it is simply
necessary to slip in place, and to seal and caulk the joints with
3-Way Caulking Compound.
