A magnetic mounting clamp sized for a D-cell Maglite torch or a pepper spray canister of similar diameter, sold singly. The magnetic base lets the clamp sit on a steel surface, such as inside a vehicle, on a toolbox, a gate post or a steel cabinet, so the torch or spray is kept in the same place and can be grabbed quickly. It is useful for security staff, farmers, vehicle owners and anyone who wants a full-size Maglite within reach rather than rolling around in a door pocket. We could not find the maker's own page for this exact clamp, so check the fit against your torch or canister before relying on it.
