Neil Pryde Boom Rear End Trim Lock adjuster (Supplied as a pair as they are handed) for the earlier X3-X6-X9 range and the current .

2 x Adjuster Clip and 2 x Barrels supplied.

All now in Blue unless otherwise stated.

Please measure your rear end tube diameter and the boom arm that the barrel fits onto (you will need to remove the barrel to do this). Remove the adjuster by carefully prizing it off. Stand the boom arm in a cup of boiling hot water to expand the barrel and soften any glue, leave for a couple of minutes and then twist off the barrel. 

Four Sizes available to cover both current and older Neil Pryde Booms. 

The 1st measurement is the diameter of the barrel where the boom Rear End tube enters and the 2nd is the barrel diameter to fit onto the boom arm.  Do ask if you are not sure about any of this!
