In the old days, fire exits were an unheard of concept. If a public building caught fire, the people inside had to escape through doors and windows. During the 20th century, fire exits became common as governments began to make it mandatory for buildings to have them. The push bar is an invention that allows for emergency exit doors to be opened with just a little push. It is illegal to have locks installed on emergency exits these days, but push bars are allowed. Locksmith Key Shop can install one for your commercial property or residence if you’re living in the Raleigh, NC area at an affordable price.
