Lifetabs are single use tabs that adhere to the strike plate on a door jam, preventing it from locking. Keeping police, EMS or and other first responders safe onscene. The brightly colored tab not only allows access to backup units but also serves as an indicator as to the location of the officer. Lifetabs are especially useful in apartment complexes where there may be multiple doors of the same color or poorly numbered doors.  Made by Cops for Cops.  Made in the USA / Patent Pending.
