Both the Catchmaster Easy Set Rat Snap Trap (621P) and the Trapper T-Rex would really be comparable in terms of bite pressure and snapping strength. The bait cup is the biggest difference in these two traps: the T-Rex bait cup is removable from the bottom of the trap, while the Catchmaster trap has a hole on top of the trap to expose the bait cup from above.
