Help with one measurment on trap.

[slipperyd12]

Hi everyone

I am building a trap for the front of my loft. It looks like the sputnik. I am down to making the squares they jump down through to get back in. Looking at other posts the width between the bars seems to be 4 and 1/4 inches, does that seem right and how tall should the opening be?
Thanks for the help!!!

I have a drop trap that I've not installed yet. It looks like the openings are right at 4 inches. The holes were drilled at about 4 1/8 to 4 1/4 inches apart.
Good luck,

They are about 7 or 8 inches tall
