Abstract: An Advanced Emergency Duty Exit Securing Strip having length and elasticity enough to hold open almost any exit device is made of a thin, tough elastomer. A first handle-adaptive hole provides multiple methods to secure a door knob, handle, pushbar, magnetic closure or lever on one side of the door. A constriction slot adjacent the handle-adaptive hole prevents inadvertent loosening of looping methods for securing a door. A latch-enveloping middle portion of the Strip has width and puncture strength enough to cover a door's latch-bolt and strike plate or other latching portion and restrain any spring-bolts or latches from engaging. The remaining handle-adaptive end portion of the Strip wraps around to the far side of the door and secures the far side door mechanisms using one of the multiple methods. Depending on door tolerances, the door will either wedge open or the exit device will be prevented from engaging.

Abstract: A Disposable Emergency Duty Latch Disabling Strip having length and elasticity enough to fit around almost any door jamb security mechanism is made of a thin, tough elastomer. A first handle-adaptive hole fits around a door knob, handle or lever on one side of the door. A latch-enveloping middle portion of the Strip has width and puncture strength enough to cover a door's latch-bolt and strike plate or other latching portion and restrain any spring-bolts or latches from engaging. The remaining handle-adaptive end portion of the Strip wraps around to the far side of the door and is attached to the far side door mechanisms using the remaining handle-adaptive hole. Depending on door tolerances, the door will either wedge open or the lock will be prevented from engaging. The Strip resists heat, cold, shearing, abrasion and can be folded to deploy from a dispenser, belt or pocket.
