it is 15 x 15 x 42. just got one and it is pretty difficult to set the trigger hook to set the trap. i need to really pull that door up tightly to get the 'double-paneled' door hi enough so the hook can hook onto it to hold it in the 'set' position. THEN there is not much movement in the hook to allow me to move it forward to get the hook well under the wire of the door (get it?) I KNOW you don't want a real nice hooking of the door. after all, the trap has to trip, right? but this just seems that there isn't enough to really set it well. It is just barely, barely holding the door open, or it just slips right off the hook and closes--ONCE i get the door pulled hi enough to latch it that is. anyone else.
