Discourage AED tampering and theft with the Philips HeartStart AED Defibrillator Secure-Pull Breakaway Seal. Intended to deter theft and indicate tampering, this set of secure-pull plastic seals are easy to break away for use during an emergency. Recommended for all customers purchasing the Philips AED Wall Mount, this seal allows users to tether their defibrillator carry case to the wall mount. A broken seal indicates that the defibrillator has been removed or tampered with, and that accessories may need to be replenished.
