Using the Easy Comply Fire Extinguisher Cabinet is straightforward. First, follow the installation steps: cut an opening with the template, insert the cabinet, tighten the screws, and secure the fire extinguisher with the velcro strap. When using it, just open the cabinet and grab the fire extinguisher in case of a fire. As for maintenance, check the cabinet regularly to make sure it's in good condition and the screws are tight. Also, keep an eye on the fire extinguisher's expiration date. Remember, this product ships in a package quantity of 2, so you'll have two cabinets at once. Make sure to install them in appropriate locations in your commercial space to meet safety standards.
