Hunter might.
It's worth a call to Hunter Marine. You could also check the "Forum Archives", search on an exact match for "loos gauge" for "All Models". You will get several hits. A rule of thumb is 15% of the shroud/stay rating. So if you have a 1/4" wire rated at 3000# the tension would be set at 450#. Another option is to study the Brian Toss rigging website.
