"Single 6m-long webbing Tradesman ratchet tiedown with keeper-type hooks (preferable when tieing loads down onto truck side-bars of slightly larger diameter). Another advantage of the keeper-hook is that it can not drop off the rail if the load becomes loose (on rough road for example). This tie-down is suitable for heavy trailer, or medium commercial loads. 50mm strap rated at 2,500kg break-strength.
