Power Post
The Power Post is a compression-based edge protection post that fixes between a structural surface and a concrete slab without bolts or permanent anchors. The compression thread is tightened using a hex head, which is accessible from the outside of the post. As the slab cures and begins to relax, the compression can be re-adjusted on site without dismantling the barrier. A load indicator is visible through the Steel Mesh Barrier, so site supervisors can confirm that compression is maintained without removing any components.
Friction-erection edge protection scaffolding of this type is used where drilling into the concrete face is not permitted or where the speed of installation is a priority. The Power Post reaches a maximum span of 3.5 m between top and bottom contact points. For taller structures where the distance between the top of the slab and the underside of the slab above exceeds 3.5 m, the Power Post Extension (code 74439, 3.1 kg) increases that reach to 4.2 m.
The compression thread on the Power Post is protected by a steel tube that prevents accidental damage during installation and on-site handling. This protects the thread form, which is the critical mechanical feature that maintains the clamping force providing temporary edge protection to the slab edge. Altrad Generation hires and sells the Power Post and Power Post Extension throughout its UK and Ireland branch network.

Frequently asked questions
Q: What is a Power Post in edge protection?
A: A Power Post is a compression post used in friction-erection edge protection systems. Rather than being bolted or drilled into a structure, the post is jammed between two surfaces using a threaded compression unit at its top. The Combisafe Power Post has a hex-head accessible from the outside for adjusting compression, a load indicator visible through the mesh barrier, and a steel-tube-protected thread. It is available in two lengths, with the extension variant (code 74439) reaching 4.2 m between contact points.
Q: How does a compression post work in edge protection?
A: A compression post is placed vertically between a lower surface (typically the top of a concrete slab edge) and an upper surface (such as the underside of the slab above or a structural header). The compression thread is then tightened, expanding the post length until the post is locked in place by friction between the two surfaces. The Combisafe Power Post compression mechanism is accessible through a hex-head fitting, and the load indicator confirms that adequate compression is being maintained. As the concrete relaxes after curing, the compression is re-adjusted on site.
Q: What is the difference between a standard safety post and a Power Post?
A: A standard Combisafe Safety Post is inserted into a clamp, socket, sleeve, or base unit that is fixed to the structure by mechanical or friction means. The Power Post uses the compression friction-erection principle, spanning between two surfaces and relying on the compressive force to hold the post in position. The Power Post is preferred where drilling or clamping to the structure is not feasible and where the inter-surface distance is within the 3.5 m (or 4.2 m with extension) range. Standard posts offer a wider range of fixing options across different structural types.
