These Rubber and Plastic Protective Corner Guards are for load securement usage only. They are used to protect edges and corners on cargo and lower the wear on tiedown belts going over loads. Rubber guards are used to increase friction to prevent movement of cargo. Metal corner caps can be used with tiedown chains.
Standards require: An edge protector shall be used where a tie down would be subject to abrasion or cutting at the point where it touches an article of cargo.
These items are not to be used for edge protection for lifting.
