Klimo and Bongartz, an embossing and enamel works near Hamburg, have been producing pedal bins for use in hospitals, doctors' surgeries and laboratories for more than fifty years - their technical design and workmanship is excellent.
The frames are made of hygienic, easy-care stainless steel; the removable buckets are stainless steel. All functional parts can be replaced. The lids are airtight and close onto a rubber ring, but the pedal can be fixed to keep the lid open.

The original.
With a pneumatic lid brake.

Many have tried to imitate the original pedal bin developed in the Fifties with a patented pneumatically dampened lid brake. The open lid drops down very slowly to prevent bacteria, dust and ash from being disturbed.
