C-channel connector mount for foundation wall 300x55 galvanised

C-channel connector for fence gravel board is a robust mounting component designed for the permanent attachment of concrete gravel board panels to fence posts. Engineered for gravel boards with dimensions of 300 × 55 mm, it provides a precise fit and stable seating of the panel regardless of ground conditions and weather.

The product is manufactured from steel with an electro-galvanised coating, giving it a distinctive silver, metallic appearance. The zinc coating effectively protects the steel against corrosion, moisture, and atmospheric conditions, ensuring long-lasting durability without the need for additional maintenance. The raw, industrial finish complements the aesthetic of modern galvanised panel fencing systems.

Construction and installation

The C-channel has a C-shaped profile into which the concrete gravel board is seated. The outer width of the profile is 57 mm, allowing the 55 mm thick panel to be placed freely and securely with a small installation clearance to facilitate fitting. The built-in cross rod Ø 6 mm acts as a retaining lock — preventing the gravel board from sliding out of the bracket, enhancing the durability and safety of the entire fence structure.

Two mounting holes in the form of 6 × 12 mm slotted openings allow the C-channel to be quickly screwed to the fence post. The elongated shape of the holes permits positional adjustment during installation, significantly speeding up the work of the installation team and making it easier to align the gravel board line on uneven ground. The flat base of the C-channel protects the concrete panel from mechanical damage during fitting.

Applications

The C-channel is a versatile component used in the installation of residential, industrial, and allotment fencing. It is ideal wherever a concrete gravel board of 55 mm thickness requires secure fixing to a fence post. Thanks to its straightforward design and adjustable mounting slots, installation is quick and requires no specialist tools — standard bolts and a spanner are all that is needed.
