JustiFix®
Adjustable decking substructure support for 35mm-500mm height.
This system greatly reduces assembly time as JustiFix® is height adjustable from 35-500mm*, making setting out and accurate levelling of the substructure a significantly easier and quicker task requiring minimum skill.
JustiFix® greatly reduces the risk of decay issues developing which can occur when a timber underbuilding contacts the ground. JustiFix® reduces the probability of water gathering underneath the substructure by enhancing ventilation and therefore greatly increases the durability of the substructure and the decking boards.
Summary
- Adjustable substructure height (35mm-500mm)
- Prevents the timber underbuilding from directly contacting the ground greatly reducing the risk of decay
- Enhances ventilation of the timber substructure and decking boards
