- Serrated teeth to lock the board in place
With the hollow decking range we advise to use a Locking Clip. This is a similar profile to the T-Clip but with serrated teeth which lock the board in place. This is ensures even expansion or contraction during hot or cold weather. One locking clip can be placed to the centre of each board where it hits the sub-frame. This will allow for the even expansion and contraction across the board length as shown in the diagram adjacent.
