If you need to securely fasten or cover your load, you'll need a way to attach ratchet straps, a net, or a tarpaulin to your trailer. At Winparts, you'll find all kinds of hooks and eyes for this purpose. A tarpaulin eye or rope hook can be easily screwed onto the trailer.
A lashing eye is used to tightly secure tensioning straps. The eye is recessed into the floor or wall of the cargo area so that it does not protrude and you will not trip over it. If your trailer cover does not have an eyelet, you can also easily find one at Winparts.
