These brackets are designed for timber constructions up to 1.50 meters in height.
No, you will need to purchase concrete anchors or bolts suitable for your specific concrete base separately.
It is not recommended, as the leverage exerted by taller posts may exceed the stability limits of this specific bracket design.
The gap is intentional to allow for under-ventilation, which prevents moisture from being trapped and causing the timber to rot.
The hot-dip galvanised finish provides excellent rust protection, though regular inspections are advised in high-salt environments.
Yes, once the surface is clean and dry, you can apply a metal-etch primer followed by exterior-grade outdoor paint.
Ensure the side screws are fully tightened through the sleeve holes and that the concrete anchors are properly expanded within the slab.
Check that the timber post is exactly 101mm; if the timber is swollen due to humidity, allow it to dry or lightly sand the edges.
For installation, align the base plate on the concrete surface and mark the pre-drilled holes. Use a hammer drill with a masonry bit to create holes for your anchors. Secure the base plate firmly. When inserting the post, ensure it is seated within the sleeve but remains slightly suspended from the very bottom to allow for airflow. To maintain the integrity of the bracket, periodically inspect the bolts for tightness after extreme weather events. If any minor surface oxidation appears over years of service, a quick scrub and application of cold-galvanising spray can restore the protective barrier.
