Measuring trap jaw spread.

Again... Not sturring the pot. I know the law. I know PA measures from the OUTSIDE of the jaws and almost all other states measure from the inside. I intend to follow the law so it does'nt matter to me. My question is when looking to buy traps and a manufacturer says that so and so trap is 6 1/2" jaw spread, is that inside or outside spread?

Re: Measuring trap jaw spread.

Your best bet would be to call the manufacturer and ask. Or better yet get a tape measure and go to a local supply dealer and measure the traps you have in mind.

I thought I've heard that every manufacturer measures jaw spreads in different ways (inside, outside, even jaw tip to tip). Good luck

I believe that they measure outside, the ones that don't usually state inside measurement.

Re: Measuring trap jaw spread.

Problem is that there is no industry standard on anything trapping related. Each manufacturer has their own way with measurements weather it is jaw spread or even trap size. Take a #2 trap from three different manufacturers and you will have three different size traps. There can be as much as 1/4" difference in the same model trap if the manufacturer offers both cast or stamped steel jaws.The differences aren't large but they can make a difference when you have State laws that aren't stated the same. A lot of States measure differently. Some measure inside to inside of the jaw, some outside to outside. Usually they measure across the dog but some measure which ever distance gets the largest measurement.As stated above, the best thing you can do is find someone that has the trap you want to order and measure it ,call the people you want to buy from and have them measure the trap or go to a supplier yourself and do the measuring. Here is another tidbit you might want to check. Make it a point to check with your local WCO about trap size. The one we had before our present one didn't know to measure across the dog outside to outside till I pointed it out in the regulations to him. He thought the measurement was taken from jaw tip to jaw tip.Better be sure what your WCO thinks, he is the man with the ticket book.
