Replacement Ceramic Fire Door Tubes
Replacement Ceramic Fire Door Tubes are for inserting into the Panic Bolt Unit which keeps the external or fire doors closed and when broken using a small hammer and chain the ceramic tube breaks to release the opening latch.
Replacement ceramic fire door tubes are spare ceramic tubes designed for panic bolt and emergency exit hardware that use a break-to-release locking mechanism. Unlike glass tubes, ceramic tubes shatter safely without sharp shards, making them a reliable and safer choice for fire doors and escape routes in commercial and public buildings.
These replacement ceramic tubes are fitted into panic bolt units or similar emergency exit door devices that rely on a break-to-release action. When the tube is broken with a hammer in an emergency, it releases the bolt or catch so the door can open quickly and easily. Ceramic tubes are used to reset the mechanism after each use so the panic bolt remains ready for the next emergency or drill. Ideal for workplaces, schools, hospitals and other buildings with fire doors, they are a safe alternative to glass tubes, as ceramic fragments do not leave dangerous shards.

What are replacement ceramic fire door tubes? Replacement ceramic tubes are spare cartridges used in panic bolt or break-to-release emergency exit hardware. They break to release the locking mechanism, allowing doors to open in emergencies.
Why use ceramic instead of glass tubes? Ceramic breaks safely without producing sharp fragments, reducing the risk of injury and mess compared with glass tubes. This makes ceramic preferable in schools, offices and public spaces.
Where are these tubes installed? They are installed in panic bolt units or similar exit devices on fire doors and emergency exits where a break action releases the lock.
How do I replace a ceramic tube? After breaking the used tube in an emergency or drill, remove the old tube and slide a new ceramic tube into the panic bolt mechanism so it will remain locked until the next activation.
Should I keep spare tubes on site? Yes — keeping spare ceramic tubes on hand ensures panic bolt mechanisms can be reset quickly after use, especially in buildings with multiple exits.
