Secure, protect, and elevate your outdoor structures with our heavy-duty adjustable post base — built for maximum performance and long-term durability.
This retrofit post base attaches a 4x4 wood post to existing concrete, making it ideal for decks, patio covers, pergolas, and other top-supported outdoor structures. Designed for both new construction and retrofit projects.
1" Elevated Standoff: Keeps the post off concrete to reduce moisture exposure and help prevent rot. Meets building code for outdoor and basement applications.
Slotted Base: Allows for easy positioning and fine-tuning around the anchor bolt — no more frustrating misalignments.
High Uplift Performance: Engineered to resist vertical pull, helping keep your structure anchored during wind or seismic events.
Versatile Installation: Compatible with 16d nails, #10 x 1-1/2" SD screws, or bolts (ABU version).
Crafted from 316 Stainless Steel for superior corrosion resistance — ideal for coastal areas and use with pressure-treated wood.
