Film storage hoppers are manufactured to stand independently or to be fitted within a series of bench units. We are able to provide a matching range of cupboards to special order on request. Exteriors are faced in white plastic laminate, interiors matt black. All models have a brown plastic safety bar handle. A micro-switch is fitted, wired in PVC insulated and sheathed 1mm flat TWE cable to a mains connector. This should be connected into the white light circuit. When the hopper is opened the white light is extinguished, preventing the unexposed film in the hopper from fogging. The safelights within the darkroom should be on a separate circuit.
