Buying Guide: Key Considerations For Trailer Jack Swivel Castors
- Load capacity alignment: Match the caster’s rating to your trailer’s tongue weight and expected loads. Overloading can reduce performance and lifespan.
- Jack tube compatibility: Most units fit 2″ diameter tubes. Always verify tube size before purchase.
- Wheel configuration: Single 6″ wheel vs dual 6″ wheels affects stability, turning radius, and weight distribution. Choose based on trailer size and terrain.
- Wheel material and durability: Spoked wheels are common for durability; PP wheels offer smooth movement but watch for wear under heavy loads.
- Mounting and installation: Some models require more precise alignment or hardware. Ensure you have the correct mounting hardware and space on the trailer tongue.
- Ground clearance and space: Larger wheels increase ground clearance but require more storage space when folded or stowed.
- Corrosion resistance: If you trailer in saltwater or humid environments, look for coated or corrosion-resistant materials.
- Adjustment and folding features: Folding capability can improve clearance and storage but verify that folding does not compromise strength.
