Dispensing Gun (Applicator Gun):
This is the handheld device that looks similar to a caulking gun.
It has a trigger and a plunger mechanism.
When the trigger is squeezed, the plunger advances, applying even pressure to both chambers of the resin cartridge. This ensures both parts of the resin are dispensed simultaneously and at the correct ratio.
This gun has a plunger release tab to retract the plunger and load/unload cartridges.
