This Ancra Tarp Corner Protector, part# 49913-10, helps eliminate the snagging of tarps on the corners of loads, which leads to cuts and tears.  The domed cap allows tarps, and other covering materials, to easily slide over the corners of a load.  Ancra web accessories offer high performance and durability.  Sturdy corner and web protectors prevent abrasion of cargo and cargo-securing straps and covers.  Corner protectors are not to be used as sling protection for overhead lifting.
