Alto cap tightener for 45mm (industrial) or 70mm caps. This cap tightener has rounded notches which grip the cap at the large end, and serrated notches at the small end (the 800405 has square notches for 33mm and 63.5mm Alto caps).
Can be used with 70mm tap-caps e.g. 700380.
The lug on the underside of the cap tighener can be used with many of our 3/4″ and 2″ drum bungs (for light use only, for heavier use the metal drum wrenches are more suitable).
