SHAPES Impact Posts
Impact Posts drive straight into the ground. Your crew skips the auger, the concrete, and the cure.
An aluminum Impact Post is driven into the ground and your fence post is secured over top. Drive it, secure your post and move on to the next.
The same system works across vinyl, ornamental aluminum, and unique design for PrimeAlux. One install method, three product lines.
Aluminum impact posts and L-impact corner posts are engineered to resist bending or warping to ensure long-lasting support.

Why Dealers Are Switching
One Change, Three Advantages
Skipping the hole and the concrete does more than save a step. It means a stronger hold in the ground, an efficient day for the crew, and a footprint you can actually document.
Why Drivable Holds
Stable in clay and compacted soil. A driven post seats against undisturbed soil on every side. A concrete-set post sits in a hole you dug and backfilled.
Less settling. Concrete can shift during the curing phase. A driven post is at final position the moment it stops moving.
Consistent depth. Every post goes to the same mark. No variation between the guy on the auger and the guy on the shovel.
Easier On The Crew
The trades are aging. Digging, lifting bags, and mixing are the parts that wear people out and drive turnover.
Impact Posts remove the digging and the lifting from the install. Crews stay on the job longer and finish the day with something left.
Lower Environmental Footprint
Concrete production carries a significant carbon cost. Every post you drive instead of set is concrete that never gets manufactured, trucked, or poured.
For dealers bidding work with sustainability requirements, that’s a line you can document.

Questions
Frequently Asked Questions
What is an Impact Post?
An Impact Post is an aluminum drivable post that replaces the need to dig and pour concrete.
Which SHAPES products do Impact Posts work with?
Vinyl fence, ornamental aluminum fence, and PrimeAlux privacy systems. The 2″ and 2½” stiffeners cover standard and deco rail applications. PrimeAlux uses a dedicated drivable post.
Do I need a special post to use an Impact Post?
No. The 2″ and 2½” stiffeners fit both light wall and heavy wall posts already in your inventory. The PrimeAlux Impact fits PrimeAlux posts with no adaptor.
How much time does this actually save?
Five to ten minutes per post, depending on soil. On a 32-post project that’s 2.65 to 5.33 man-hours. Across a typical week, expect roughly a crew-day back.
What equipment do I need?
A driver. Expect $2,000–$3,000 for the initial investment — less than a comparable hydraulic post hole digger.
What soils are drivable posts suited for?
Clay and compacted soils perform well — the driven post seats against undisturbed material on all sides.
What about corners and ends?
Use the L-Impact Corner Post Stiffener for corner applications on 2″ posts.
Are Impact Posts made in the U.S.?
Yes. Impact Posts are made in America.
How do I order?
