Angled Axle Bracket - Connects axle tube, upright tube, and wheel shaft.

Axle T Bracket - Connects axle tube to aft tongue tube, and joins tubes on many racks.

Handle Bracket - Supports bow (on some dollies) and provides attachment point for handle tube and grips. Use this standard bracket for dollies that do not support bow on bracket and use either the wide cup bracket or narrow cup bracket for dollies that do support bow on the bracket.

Sling Bracket - Holds sling at top of upright tube.

Sling - Support boat or kayak with padded finish. Sling available in multiple lengths.

Wheel - Standard Wheel and Large Wheel replacement wheels available.

Wheel Shaft - Bolted into Angled Axle Bracket with keeper pin on the end for wheel. Use Wheel Shaft 44101 for standard wheels.
