3/8" security chain fits best with our 2-1/2" sleeve, which can be found here (there are specs on this page as well). As for the lock, when used with 3/8" or 1/2" security chain, there really is not a gap that would allow access to bolt cutters. That is due to the design of this padlock with the recessed chain pockets. The bolt/pin is actually very well protected.
