The 5110 Replacement Bag Bottom by Ferno delivers a durable structural reinforcement layer engineered to renew ground protection on primary emergency responder kits. Fabricated from commercial-grade, heavy-duty waterproof PVC composite vinyl, this modular panel creates an unyielding protective barrier against fluid pooling, mud infiltration, and rough field friction. Tailored precisely to match the exact base dimensions of the professional Model 5110 Trauma Air Management Bag II, the resilient replacement plate installs easily to extend the active service life of high-use fleet equipment while ensuring internal life support contents stay completely clean and dry during rough outdoor rescues.
