Important Information
CONCEALoc Hidden Fastener Installation Instructions
CONCEALoc Hidden Fasteners were designed exclusively to
install TimberTech grooved and square shouldered planks.
Always be sure to check and cut the factory cut
ends of all boards to ensure they are square.
• In areas with obstructed airflow such as roofs and
on-grade applications, a minimum of 1-1/2”, sleeper system,
is required.
• Sleeper system must be supported by and connected to the
substructure over which the deck is built. DO NOT attach deck
boards to a floating sub-structure which is not mechanically
fastened frequently and sufficiently to the building and roof deck.
• To further minimize expansion and contraction, proper
ventilation and airflow should be considered.
• On-grade decks must have additional provisions for drainage
beneath the deck structure.
• For best practices, decking should not be installed in
applications where ventilation and airflow cannot be achieved.
• Do not use CONCEALoc Hidden Fasteners or L-Bracket for
stair installation.
