The Guard Dog CPRPKIT.75-20 20-piece optional anti-slip rubber pad kit contains 20 rubber pads that can be attached to the bottoms of Guard Dog heavy-duty low-profile cable protectors (sold separately) to help keep them from slipping on smooth surfaces. Rubber resists slipping and wear. This product is suitable for use with a Guard Dog GD1X75-ST, GD2X75-ST, GD3X75-ST, or GD5X75-ST cable protector (sold separately). The kit weighs 0.11 lb.Drop over cable protectors (also called cable covers or cord covers) protect cables, electrical cords, and hoses from wear and compression from pedestrian and vehicular traffic. They can also improve pedestrian safety by helping to decrease the risk of tripping over cables crossing paths or aisles. Drop over cable protectors are placed over cables lying on a floor or outdoor surface where people or cars are expected to pass. These protectors are shaped like trapezoids with an opening on the bottom (called the channel) for the cable or cord. Because they are open on the bottom, they are easy to deploy and pick up, but when used on rough surfaces, they do not protect cables from abrasion from below. Cable protectors are designed for use in public, commercial, and industrial applications where cables, cords, and hoses need to extend across an area that pedestrians may pass or vehicles might drive over.Checkers Industrial Safety Products manufactures cable management systems, wheel chocks, and warning whips for manufacturing, mining, aviation, military, construction, and entertainment applications.
