Bollard covers and post sleeves are designed to fit over the top of posts and bollards to protect them from wear and tear, and are widely used in parking areas, pedestrian walkways or perimeters around retail shops, restaurants and warehouses. Raptor Supplies offers a wide range of bollard covers & post sleeves from brands like Eagle, Post Guard, Vestil and Calpipe Security Bollards. Eagle bollard post sleeves feature strong & high-density polyethylene (HDPE) construction with UV inhibitors that resist fading, rusting and cracking. These post sleeves can easily fit over 4, 6 and 8 inch NPT pipes and also eliminate the need for regular maintenance while protecting the vehicles and the post from impact damages. They also facilitate easy slide-on installation because of their unique design.Post Guard bollard covers are designed with smooth sides and two reflective stripes, recessed near the top of the cover, for appearance and high visibility in low-lit conditions. The brand's bollard covers are made using 1/8 inch thick HDPE sheets capable of providing strong intermolecular forces, tensile strength and solvent resistance, as well as absorbing the impact loads and protecting the vehicles and structures from expensive damages.
