 FRL100 Spacer Ring Adjustment

The fit of the Excalibur can be adjusted as necessary using the supplied 10mm, 7mm & 5mm spacers in any combination as appropriate. The spacers simply screw onto the bolt. Ensure the lip of the spacer is facing towards the end of the bolt in order to retain the freely rotating collar.



CAUTION! Be careful of potential surface damage to alloy wheels when positioning/fitting the Excalibur.

NOTE: Only suitable for factory fitted alloy wheels.

A.   Offer up the Bolt Receiver arm (3) to the caravan wheel from the side.

B.   Position the Bolt Receiver (3) so that the threaded aperture is accessible through a gap in the spokes of the alloy (it may be necessary to rotate the wheel slightly).


FRL100 A and B


C.   Insert the hex tool (5) into the bolt (4). Line up the bolt to the bolt receiver’s (3) threaded aperture (see Fig.B ).

D.   If necessary, unscrew (by turning anti-clockwise) the Wheel Hub Arm Hex Bolt (7). Do not fully remove.

E.   (see Fig.A & Fig.B for guidance) 

The lock (2) is already fitted through the shield portion (1) in a locked state.

Insert the key into the lock (2), push and turn 45° clockwise to release the locking mechanism.

Fit the Lock (2) into the bolt (4), once inserted turn the key 45° anti-clockwise and remove the key.

If the key cannot be turned 45° anti-clockwise and removed, it is likely that the male lock portion cannot fully engage into the bolt. If this occurs the bolt needs to be extended using one or more of the spacers (see Fig.A & Fig.C for details on spacers).

Ideally, when properly fitted there shouldn’t be a gap any larger than approx. 5mm between the face of the alloy wheel and the back face of the shield.
