It fits onto the rear riser of parasail, when deployed into the water it should bring the parasail to a slow stop.

        It fits easily on to any size parasail and can be operated by the passengers or the parasail crew.

        Each parasail requires its own specific Wrangler deflation line, these come in various sizes  to fit each parasail.

If the Wrangler is accidentally operated it does not effect the flying ability of  the parasail, it will just require a controlled water landing.
