Wedges (A) are stackable for greater angles or to act as a riser.
Stack wedges (A) to raise height of cleats or to correct mounting alignment at 11, 22, 33 degrees.
You will need to use multiple wedge kits (A & B) if cleat angled required is greater than 11 degrees.
The smaller component is a backing plate (B) which is to be mounted under deck to distribute load and help align the nuts with the angle of the fasteners.
Only the wedge component (A) matches the base of the cleat and has locking pips to allow for stacking.
See diagram for further details on the correct set up of these parts.
A comprehensive range of speclialist cleat accessories allow customisation of the cleat setup to optimise performance by controlling inward lead, outward lead, cleating and uncleating angle and height.
