The RMHs wheel chock is a portable vehicle securing device designed
for safe parking and emergency roadside maintenance. Constructed
with high-strength aluminum alloy and non-slip rubber base, it
achieves rapid and stable wheel locking through a triangular
mechanical structure. Its key highlight is the no-bending, one-handed stand-up operation, which significantly improves safety in high-traffic or
low-visibility environments.
Lightweight and compact, it fits easily in your trunk. Whether
you're parking on an incline, driving on rainy or icy roads, or
performing tire changes, this is an essential safety accessory for
every driver.

Advantages
1. Stand-Up Operation – Safer and Effortless
Traditional wheel chocks require bending and squatting, which can
be hazardous in heavy traffic or low-visibility conditions. The
RMHs features a hand-pull telescopic design that allows for one-handed deployment and placement while standing upright. With a clear field of view and quick, decisive action, it
effectively reduces the risk of secondary accidents.
2. Triangular Structure – Powerful Wheel Locking
When deployed, the chock forms a stable triangular mechanical support. Combined with the specially formulated non-slip rubber base, it
generates exceptional friction with the ground. Whether you're
parking on a slope, driving on rainy or icy roads, or performing
emergency repairs and tire changes, it firmly secures the wheel to
prevent any unintended rolling.
3. Lightweight and Compact – Always Ready in Your Trunk
Weighing only 2.5kg and retracting to L151×W218×H816mm, it is slim and lightweight, fitting easily into the corner of your trunk without taking up
valuable everyday storage space. It's ready whenever you need it –
no frantic searching, no waiting in an emergency.
4. Forged Aluminum – Rugged and Durable
Crafted from high-strength aluminum alloy through welding and forging, with an electrostatic spray coating for rust protection, it combines lightweight portability with
outstanding strength. Built to withstand various outdoor
conditions, it delivers reliable performance over the long term.
5. Spring-Loaded Telescopic Design – Pull and Lock
The built-in telescopic mechanism enables quick and easy deployment and retraction – no tools, no complicated steps. Dimensions can also be
customized to fit different wheel sizes, making it suitable for a
wide range of 2T–4T vehicles with flexible practicality.
6. Multi-Unit Configuration – Double the Security
Supports 2-unit or 4-unit setups – securing both front and rear wheels simultaneously for added
stability. Whether for passenger cars, logistics fleets, or
off-road equipment, there's a configuration that meets your
specific needs.
Instructions for Use (Step-by-Step)
Step 1: Remove and Deploy
Take the wheel chock out of the trunk, pull the main body by hand
to extend it into the triangular support position. You will hear a
click when it is fully locked in place.
Step 2: Position and Secure
Place the deployed chock firmly against the bottom of the wheel,
ensuring that the rubber base makes full and even contact with the
ground—no gaps should remain.
Step 3: Confirm Firmness
Give the chock a gentle tug by hand to verify that it is securely
wedged against the wheel and will not slip. Once confirmed, you can
safely proceed with parking, maintenance, or tire changes.
Step 4: Retract and Store
After use, press the release mechanism to collapse the chock back
to its retracted size, then return it to the trunk for future use.

Important Notes
For maximum safety, it is recommended to use 2 or 4 units together, securing both front and rear wheels simultaneously.
Before use, ensure the ground is flat and free of large debris.
Do not attempt to move the vehicle while the chock is deployed, as
this may cause damage to the product.
Q&A
