Securing cylindrical objects can be difficult and frustrating without the right tool for the job. Smart-Jaws Tube-Fit Sleeves are engineered to provide a secure grip on suppressors, PVC and cast-iron pipe, and all types of tubing, and are two-sided to best fit the application. For delicate items such as suppressors, the non-marring, soft jaws apply ample gripping and torquing power to loosen the tightest fits without damaging your investment. For tough jobs when marring is not an issue, such as with cast-iron pipe or steel tubing, simply reverse the jaws to the steel side for the ultimate vise-like grip.
