Trigger pressure on all of the Comstock traps can be regulated. Not only can trigger pressure be varied on the 9×11, 12×12 and 12×18 heavy duty beaver trap, variability is even possible with the newest swing panel squirrel type traps. Each of the cage traps is designed to have light trigger pressure for most common uses, squirrels and chipmunks, but additional pressured can be added to the swing panel squirrel type traps, from the smallest 3×5 up to the largest 8×10 trap for rabbits.
Additional spring pressure will make the trap a bit stiffer, requiring more pressure to fire. Springs can be stretched for more tension and hooked lower on the door and conversely can be relaxed for lighter pressure. The simplicity in these traps allows for additional springs to added to increase pressure. The larger traps already have 2 springs, while the smaller traps have 1.
Since the contact point on these traps is two galvanized rods, even a piece of tape on one element could have a similar effect.
