NBJINGYI 6" Dual Trailer Jack Caster Wheel — 2,000 lb Capacity, Fits 2" Jack Tubes, Twin 6" Poly Wheels

The NBJINGYI 6" Dual Trailer Jack Caster Wheel converts a standard 2" tongue jack into a smooth, steerable rolling caster that supports up to 2,000 lbs of tongue weight.

Move trailers, pop-up campers, and small utility rigs by hand with far less effort. This bolt-free caster slips over a standard 2-inch jack tube and secures with a heavy-duty safety pin, giving you instant mobility for positioning, storage, or light maneuvering without calling for extra hands or repeated jacking. The twin 6-inch poly wheels spread load and resist digging on soft surfaces like grass and gravel, while the 360-degree swivel lets you make tight turns in crowded yards or garages.

How does the dual-wheel design improve movement on grass and gravel?

Dual wheels increase surface contact and distribute the tongue load across a wider area, which reduces sinking and rolling resistance. This design helps the jack roll over small stones and softer ground without catching, so you can push or pull trailers more predictably.

• Twin 6" poly wheels for wider ground contact and better flotation
• Reduced rolling resistance on packed dirt, turf, and gravel
• Improved lateral stability to prevent tipping while turning

Will this caster fit my trailer jack and hold my trailer safely?

The caster is built for standard 2-inch inner jack tubes and is rated to support a 2,000 lb tongue capacity, suitable for most pop-up campers, small RVs, and compact utility trailers. Always confirm your trailer's tongue weight and follow safe attachment and storage practices before towing on public roads.

• Designed for standard 2-inch jack tubes—no adapters required
• 2,000 lb tongue weight rating for light-to-medium trailers
• Heavy-duty safety pin locks the caster in place during use

How easy is it to install and remove the NBJINGYI caster?

Installation is tool-free and quick: slide the caster onto the jack tube and insert the supplied high-tensile safety pin. Removal is just as fast—pull the pin and slide the caster off to restore proper towing clearance before driving.

• Tool-free attachment using included safety pin
• Fast on/off for quick transitions between storage and towing
• Compact design for simple stowage in your truck bed or storage compartment

How does the swivel action affect maneuverability in tight spaces?

The 360-degree swivel caster lets you pivot the trailer smoothly, making precise adjustments when parking, aligning hitch couplers, or rearranging trailers in storage. The combination of swivel action and dual wheels helps reduce the need for multiple truck repositioning.

• Full swivel for tight turning radiuses and precise repositioning
• Stable wheel spacing keeps trailers tracking straight while pushed
• Works well on concrete, asphalt, packed dirt, and maintained turf

Who is this for: The NBJINGYI dual caster is aimed at owners of pop-up campers, small travel trailers, and 4x8 utility trailers who need to move or store their rigs without extra labor or equipment. It’s ideal for weekend campers, DIY backyard storage, marina berth maneuvering, and anyone who wants a safer, easier way to align hitches and reposition trailers in tight or soft-surface locations. Always verify your tow vehicle and trailer weight specs and remove the caster before highway travel.
