Recommended Fitting

Ut nulla sem, tincidunt et fermentum a, adipiscing eget velitusce eu sagittis nisi varius.

It is recommended that the initial fitting out of the vehicle is done in the course of scheduled maintenance or during a roadworthiness inspection or when a wheel nut torque check is scheduled.

The wheel nuts must be torqued to the recommended value before the Checkpoints® are fitted.

The Checkpoint® should be a tight slide fit onto the wheel nut without the need for tools or any other assistance. This is also the case when there is a need to remove them.

Fit the Checkpoint® so that the raised rim of the collar is outermost from the wheel nut washer, or the profile of the wheel. This eases removal by giving a finger purchase on the collar rim of the Checkpoint® without damage.

The layout pattern used for the Checkpoint® on the wheel is of personal choice; it is often dictated by the wheel rim size and profile, and/or the PCD of the stud.

The most commonly used patterns are:

Any patterned configuration may be used so long as the movement away from the set pattern of one or more of the Checkpoint® will be clearly visible on inspection.

Safe Configuration

Unsafe Configuration

Important Reminder

When arranging the pattern you will use as the layout for the Checkpoint® on the wheel, that should a wheel nut loosen off, the Checkpoint® pointer needs room to move to indicate that the wheel nut has moved; this is normally anti clockwise. The length of the pointer should not therefore be aligned against the wheel rim profile, which could restrict movement.

Material Grade

Ut nulla sem, tincidunt et fermentum a, adipiscing eget velitusce eu sagittis nisi varius.

Checkpoint® is manufactured from Polyethylene. This special grade is suitable for heavy-duty applications such as high load urban duty cycle service or where full axle loading is the norm.

Checkpoint® is designed to distort and melt at a vehicle hub/stud tempreture of 125 degrees centigrade. In addition for further severe operating conditions Checkpoint® have a high temp product with a distort/melt point of 135 degrees centigrade.

The material used is a virgin polymer and is UV stabilised. It is therefore dimensionally stable. The polymer does not degrade in sunlight. Checkpoint® can be cleaned using any of the available vehicle cleaning agents, detergent solutions or paraffins.

Checkpoint® are not attacked by road salts or petrochemicals. The pointer being large, it is highly visible even when coated with road or operational grime.
