Alto cap tightener for 63.5mm or 33mm caps. This cap tightener has square notches which grip the cap at both ends (the 800406 has rounded notches for the 70mm, and serrated for the 45mm Alto caps).
Can be used with tap-caps e.g. 700744.
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).
