Baffle Bones

By Global Rotomoulding

Each Baffle Bone has a large surface area and low volume (displacement). This unique shape is a single-piece injection moulded part that is strong enough to withstand the sloshing force of water in a tank and requires no assembly. When many Baffle Bones are used together, the combined high surface area of the Baffle Bones provide a significant reduction in the movement of water within the tank, dramatically improving vehicle handling. Baffle Bones meet the Load Restraint Guide (RTA) criteria and have been independently tested and certified.

We recommend the Baffle Bone system be used in all tanks with a volume greater than 2,000 lt.

Baffle Bones:

  • Small Baffles made from natural High Density Polyethylene (HDPE), Large from Low Density Polyethylene (LDPE)
  • Low volume, high surface area
  • Recommended for all tanks over 2,000lt
  • Assists in the reduction of water movement while braking and turning.

  • Thank you so much for being so helpful with our tank purchase and delivery. Raining now and water dripping into our new tank Bert and Jane Mol
  • Right from the start I dealt with courteous, knowledgeable people who answered me promptly. The icing on the cake was Steve, the delivery driver, whose truck arrived within 1 minute of the ETA he gave me and popped the tank off in the right place with a mere flick of his crowbar. This company gives professional service all the way. I am So Happy. Dave Burns
