04230 Billet Loop- such a great looking addition to a back billet on a saddle and so easy to install. This loop is meant to be sued on the back billet of a saddle replacing the usual leather loop. There are 2 windows thru the back of the loop should you decide that you want to speed rivet the leather thru those window as. But in fact even that is not really necessary. The metal loop can simply be captured between the fold and it will stay in place and do its job without fail.
