Fitment Guidance Critical weight support note: The DW85H is designed to hang from cargo barriers while being fully supported underneath by the vehicle floor. The hanging points help maintain shape and position — they are not designed to carry the full water weight (approximately 85kg when full).Best practice for installation: Ensure the bladder rests on a solid surface such as the cargo floor or drawer system. Use the hanging points to secure the bladder in position and prevent shifting. For vehicles with uneven floors, use plywood or sheeting to create a supportive base. Never suspend the bladder by hanging points alone. The bladder will flex and mould naturally to available space as it fills.Note: Proper floor support is essential for safety and to prevent damage to the bladder or hanging points.
