Making bondage belts is one my favorite things to do! These will certainly get the job done too! Made from 2" wide leather, all 6 belts in the set come with a nickel plated buckle, D ring, and locking pin. I do offer the locks too if you need a set. Belts come in requested lengths up to 60". Set is $299.
For ultimate security, you may find my Backbone Body Harness a bit more desirable. ;P
