A518. "Bar Lock Crushproof" Double Reinforced Concrete Sidewalk Light Construction The "Bar Lock Crushproof" cast iron
shield protected glass makes it the most durable sidewalk light
ever placed on the market in our 30 years' experience in this
line of business. Especially designed for use where permanence,
freedom from broken glass, leakage and maintenance charges are
appreciated.
Made in completed factory finished
slabs ready to drop over the openings, or we will send our own
mechanics, if preferred, to install in the field anywhere in the
United States.
The cast iron shield insures an
absolutely water-tight joint under and around the glass, and the
flange on the outer surface insures a perfect anchor in the
concrete.
The heavy body of reinforced concrete
does not come in contact with the glass, eliminating another
previous cause of breakage of glass from expansion.
The cast iron shields are solidly
embedded in the heavy concrete construction and will last for
the life of the building. Special Features of "Bar Lock Crushproof" Replaceable Construction Replacement—it is practically
impossible to entirely prevent cracked or broken glass from
accident or abuse, but a cracked or broken lens in the "Bar Lock
Crushproof" construction may be replaced by unskilled labor in a
few moments. There is no cutting of concrete, unsightly patchwork
or likelihood of leakage.
The importance of this replacement
feature will be readily appreciated.

construction is made not only from a specially prepared, tough
mixture, but each piece is separately polariscope tested, which
effectually prevents all cracking or breakage from expansion or
contraction. The lenses, being of pure crystal annealed glass
with sunburst or Fresnel-lens undersurface, insure the largest
light transmission and diffusion.

Reinforced Concrete Construction, using Lazalite polariscope
