Drum Covers provide an inexpensive way to convert open-top 30- and 55-gallon steel drums into fire-safe receptacles for combustible trash. Only a screwdriver and wrench are needed to attach the cover to a drum, and it can easily be removed when the drum must be emptied. Covers are steel, with a highly chemical resistant powder coat paint finish. 30-gallon cover will fit drums nominally 18.375" diameter. 55-gallon size will fit drums from 22.5" to 22.75" diameter. On models 26730 and 26750, a replaceable fusible-link assembly inside the cover melts at 165°F to automatically slam the cover shut if there is a fire in the drum to extinguish the flame.
