Throwing a Little Light on
The Mullen Replaceable
Vault Light Sidewalk.
A Broken Glass in a MULLEN sidewalk, means a broken glass — not a Damaged and Broken Sidewalk.
The Mullen Replaceable Vault Light Sidewalk is made on a new principle. Each glass light may be removed and replaced in a few minutes WITHOUT injuring the cement.
The Mullen lights throw a wide beam of light into the vault, making the basement really LIGHT.
The Mullen Sidewalk costs less, wears better, gives more service.
You can see one in course of construction at the Farmers Bank Building.
If you are building or contemplate repairing your walk, write, call or telephone for particulars.
