Bubble level for tripod 35 to 45 mm

Description

This bubble level fits on a tripod in order to check that it is set level before taking a measurement. It replaces a broken or missing bubble and gives the tripod back its reference function, without which the set-up has to be checked another way. Mounting is provided for tripods whose diameter is between 35 and 45 mm, the Leica TRI120 being cited as an example; outside that range, fixing is not assured.
