Looking for strong, reliable structural connectors and fixings for your construction projects? Simpson Strong-Tie offers high-performance joist hangers, angle brackets, straps, anchors, and screws—all engineered for safety, durability, and ease of installation. Manufactured in the UK and rigorously tested to meet British and European standards, these products are ideal for timber framing, decking, masonry, and steel connections. With expert support, fast delivery, and innovative solutions like Quik Drive® screw systems, Simpson Strong-Tie provides trusted, code-compliant products for builders, contractors, and engineers across residential and commercial projects.
The Simpson Strong-Tie ABW Adjustable Post Base with Stand Off is a versatile and cost-effective solution for anchoring timber posts to concrete surfaces. Designed to elevate the post 25mm above the concrete, it helps prevent moisture-induced decay, extending the lifespan of the timber.
Key Features:
Adjustable Installation: The slotted base allows for flexible positioning around the anchor bolt, accommodating various post placements.
Retrofit Capability: Suitable for both new constructions and retrofitting existing structures, it can be installed onto a threaded bar in poured concrete or with a resin or mechanical anchor into solid concrete (anchors sold separately).
Durable Material: Constructed from pre-galvanised mild steel, offering corrosion resistance for outdoor applications.
Enhanced Post Protection: The 25mm stand-off design reduces the risk of moisture-related decay at the base of the timber post.
Ideal for applications such as pergolas, carports, and other timber structures, the ABW Adjustable Post Base provides a reliable and durable connection between timber posts and concrete foundations.
