Why Use a Matched Fixing System?

Correct sub-frame spacing and hidden fixings protect the board longevity, improve slip resistance and reduce movement. Adjustable pedestals simplify levelling on patios and hard standings while preserving airflow beneath the deck to reduce moisture build-up.

Using specified clips also ensures consistent expansion gaps through seasonal changes, contributing to a stable, low-maintenance deck that looks smart year-round.
