Hidden Fastener Installation System

The Castlewood hidden fastener system features two clips, one locks and secures the board down ( Locking Fastener ) and the other allows for expansion and contraction ( Control Expansion & Contraction

- CEC Fastener ), so that you don’t experience warping or distortion of any kind after installation. The system works because it allows the user to control the direction in which the expansion and

contraction will take place.

TC1 - Locking Fastener
TC2 - CEC Fastener
TC5 - Start/End Fastener

The illustrations below show the basic examples of placing Locking and CEC Clips when installing a different number of Castlewood decking boards.

 

In simple terms the locking fasteners should always be used in the middle or near the middle of the boards. Start/End Fasteners should be used at the first and last rows only.
