Description

Reliable 450mm Dual Axle Wheel Chock for Caravans, RVs, and Trailers With Interlocking Design and Rubber Grip Base

Safety comes first when parking your caravan, RV, or trailer. The Supex 450mm Dual Axle Interlocking Wheel Chock is designed to secure your vehicle in place, preventing unwanted movement and giving you reliable protection every time.

Designed for tandem axle caravans, this heavy-duty chock sits securely between the tyres, creating a solid barrier that helps prevent rolling, shifting, or sinking.

It holds your caravan steady and level during overnight stays, long-term parking, or storage even on soft or uneven ground.

Made from tough poly material, it’s built to last through long trips, varied weather, and rough terrain.

A rubber grip along the base improves contact with the ground and helps keep the chock in place, even when surfaces get slick or uneven.

The dark grey colour blends in well with most caravans and trailers and hides dirt and scuffs. It’s easy to use too—just position it between your dual wheels, and you’re good to go.

If you’re working with a single axle setup, no worries—this chock can be separated and used as two single chocks, giving you flexibility for different vehicles or storage situations.

At 450mm long, 209mm wide, and 119mm high, it’s a solid, reliable piece of gear that doesn’t take up much space in your kit but offers big value when it comes to stabilising your setup.

Simple, smart, and built for Aussie conditions, it’s a must-have for anyone who takes caravan safety seriously.
