C-channel connector mounting bracket for kerb 300x50 galvanised

C-channel connector for fence gravel board is a robust fixing component designed to permanently secure concrete gravel board panels to fence posts. Engineered for gravel boards measuring 300 × 50 mm, it provides a precise fit and stable seating of the panel regardless of ground conditions and weather.

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

Construction and installation

The connector has a C-shaped profile into which the concrete gravel board is seated. The external width of the profile is 52 mm, allowing the 50 mm thick panel to be inserted freely and securely with a small installation clearance to facilitate fitting. The built-in cross rod Ø 6 mm acts as a locking bar — it prevents the gravel board from sliding out of the bracket, increasing the durability and safety of the entire fence structure.

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

Applications

The C-channel connector is a versatile component used in the installation of residential, industrial and allotment fencing. It is ideally suited wherever a 50 mm thick concrete gravel board 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.
