***MASK BELTS WITH ANTI-SLIP BANA *** Made of high-density polyester and high quality metal buckle, it is highly stressed and does not break easily. They can withstand more than 800 pounds and the increased anti-slip band design can avoid breaking during movement and prevent falling and bumping furniture. *** TWO MODES OF USE *** The motion sliders have two modes of use (arm and shoulder mounted). For heavy and large appliances, we suggest combining the shoulder harness and lifting straps together. The lightweight but irregular object could use lifting straps with the arm, the foam pad can prevent pressure and relieve pain. ***ADJUSTABLE STRAPS *** The lifting straps width is 2 inches, and the length can be easily adjusted from 50" to 130". Approximately 39 oz (1.1 kg). Thanks to the seemingly limitless adjustability of the buckle strap, regardless of size or shape, you can lift them properly and easily. ***COMFORT AND COMFORT *** With sponge shoulder pads on the lifting straps and two auxiliary shoulder straps. Helps reduce the risk of injury by using proper body mechanics to prevent heavy objects from grazing your arms during movement and to relieve back and shoulder pain from heavy, repetitive lifting. ***MULTIFUNCTION *** Lifting pens are portable and convenient to store in a drawer, tool box or under the seat of a truck. The straps are especially good for transporting office partitions, desks, cabinets, cabinets, safes, sofas, woodworking tools, hot tubs, mattresses, furniture, appliances, cars, heavy-duty units, cast iron tubs, etc.
