6.0t ATM Galvanised Bow Shackle – Suit 13mm Tow Bar Chain

Bow shackles are often used instead of D-Shackles on off-road trailers, caravans, and camper.

Selecting the right bow shackle for your application (such as rating and size) is important, as undersizing/oversizing can lead to complications. Couplemate™ recommends this galvanised bow shackle for applications over 2500kg but not exceeding the 6000kg ATM capacity.

For the trailer side, the Couplemate™ CM551-3 Safety Chain Holder is a popular drawbar connector.

D-Shackles vs Bow Shackles | Which is Best for Off-Road & 4WD?

Bow Shackles are very similar to D-shackles in that they connect the trailer chain to the drawbar through a rated pin. However, due to their design, Bow Shackles are better for off-road caravans, trailers, and campers.

The shape of a bow shackle offers better, more even chain articulation and spread.

Comparison of galvanised D-shackle (dee shackle) vs a bow shackle shape and design.

Bow shackles have a rounded “O” shape, whereas D-shackles resemble the letter “D.”
