7" Wide Plastic Bollard Sleeves are made from durable 1/8" thick High Density Polyethylene (HPDE) which provides tougher tensile strength and solvent resistance. They easily fit over existing bollard posts which means fast installation without adhesive tapes, foam stripes or gripper tabs. Each bollard sleeve features two reflective stripes for increased visibility and safety. They're available in multiple colors and heights as well as with a variety of different tape colors.
