Hasp and padlock size

[56Chicks]

Hello all, I have just a quick question re: predator proofing. I am looking to add latches and padlocks to the external nest box on my customized shed. It has kind of a spring lock in the center but I would like to add hasp latches and padlocks on each side in case the raccoons return to the area. What size hasp locks do you all use, and what size padlocks fit the hasps? Quarantine in my area means I can do a curbside pickup of animal supplies but I can’t see the items in person before ordering. Thanks so much for your advice!

I use 3 1/2" HASPs, they seem to fit perfectly for everything coop related I've needed them for.

I have no idea on the padlock size though. I usually use these "screw close quick link":

You could just get an adjustable padlock
