Erickson Recovery straps all feature a sewn end loop with an overlay of high-tenacity nylon to ensure longer life in the pull area, where most of the wear occurs in this type of towing system. The sewn loop also makes it easier to attach the strap loop to the tow hooks on the vehicle. A lot of other models from different manufacturers do little or nothing in the pull area as it is certainly time-consuming and a definite added cost. Heavy-duty webbing is rated at 10,000 lbs. per inch of width: the wider the web, the stronger the strap. A heavy, 415 series thread is used in the sewing process to ensure the advertised load limit is met or exceeded.
