A fire resistant shutter is provided including a first panel including wood and a second panel including a cementitious material located adjacent to the first panel. The fire resistant shutter further includes a hasp attached to the second panel and configured to be attached to a building structure with a detachable connector, and a pin including wax disposed in an aperture defined by the hasp. The pin prevents the hasp from opening. When the fire resistant shutter is attached to a building structure, heat from an approaching fire at least partially melts the pin, which opens the hasp, detaches the connector, and allows the shutter to drop. The deployed shutter provides fire resistance to the building structure, such as at a window.

A pass through closure and delivery device permitting material to be safely passed through a slot in a partition or prison cell door. A container having first and second openings and first and second doors associated with each opening is disclosed for mounting on a partition or cell door having a slot therethrough. Each door on the container includes a latch that is operable from only one side of the cell door. A cam-operating attaching mechanism allows the container to be releasably mounted to a pair of track members affixed to the cell door with the slot therebetween. Using the pass through delivery device and the method of the present device, food or other materials can be safely delivered to an inmate inside a locked cell by mounting the container of the pass through delivery device on the cell door with one of the openings adjacent the first door covering the slot in the partition. The second door is then opened, allowing a guard or delivery person to insert a food tray or other materials to be delivered into the container. The second door is then latched shut and the first door is then opened to allow the prisoner access to the food or other materials through the cell door slot and the first opening in the container. After the inmate removes the food or material from the container, the first door is again shut and the container can be removed from the cell door.

An improved security door is provided that is a composite of multiple layers. The layers include a first hard layer, a second hard layer, a reinforcing layer disposed between and connecting the first and second hard layers, and a carbonizing layer provided adjacent the reinforcing layer. Other layers, either singularly or in combination, can be included to make the security door further resistant to penetration by various tools. The other layers can include a clogging layer, a mobile layer, a resilient layer, and further reinforcement layers.
