Includes: Set of 20 three-hole trailer net hooks. The hook measures approx. 5 x 4 x 2.5 cm (L*W*H). Each hook has three ø5 mm screw holes. Strong material: Our tension hooks made of 3 mm thick pressed galvanized iron are particularly durable and can easily carry even very heavy lashing straps. Safe! Hold: The flat support surface and the three-hole design ensure a secure hold when mounted on the side wall of the trailer. Wide range of uses: The tension hooks are suitable for attaching tarpaulins, tarpaulins, trailer nets, cargo nets and lashing straps. You can mount them on the tailgate or on the side walls of the trailer. You can also use the three-hole hook as a normal hook.
