iSaddle Dual Trailer Jack Wheel Dock — 6" Nitrile Rubber Double-Wheel Stabilizer, Non-Slip Drain

If you use a trailer, RV, boat or pop-up camper, stabilizing the swivel jack wheel is essential to protect the jack and keep your rig level. The iSaddle dual wheel dock is molded from durable nitrile rubber to distribute weight, resist oils and abrasions, and provide a non-slip base for dual caster wheels. A built-in drainage channel helps water escape so the jack wheel stays dry and corrosion risk is reduced.

How does this dock chock stop my jack wheel from sinking into mud or sand?

The wide, low-profile design spreads the trailer tongue load over a larger surface area, reducing ground pressure that causes sinking. The textured underside bites into soft surfaces while the outer lip resists sideways slippage, keeping your trailer steady.

• 6" diameter contact area disperses weight across a broader footprint
• Heavy nitrile rubber resists deformation under load
• Textured base increases grip on dirt, sand and gravel

Will this fit my swivel caster dual wheel jack?

iSaddle recommends pairing this dock with 6" (150 mm) swivel jack dual wheels, but it also fits many similar solid wheel profiles on the market. Confirm your jack wheel diameter before ordering to ensure an accurate fit and optimal performance.

• Designed for 6" (150 mm) dual caster wheels
• Compatible with many solid dual-wheel jack casters
• Simple fit—slide wheel into the dock and seat fully

How does the dock protect the jack wheel from dirt and corrosion?

The waterproof nitrile rubber resists oils, grease and road grime that can abrade or contaminate the wheel. A drainage hole channels rainwater away, helping prevent standing water that could accelerate rust on metal jack components.

• Nitrile compound offers oil and abrasion resistance
• Raised rim shields wheel sides from mud and debris
• Built-in drain reduces pooled water and rust risk

How easy is it to use and store the iSaddle dual wheel dock?

Its compact, lightweight geometry allows quick placement under the jack wheel and equally easy removal for storage. The rubber construction nests well with other gear and won't scratch surfaces like harder chocks can.

• Quick slide-on installation—no tools required
• Stackable and compact for neat storage
• Durable for repeated seasonal use
