Description
Gravel board bracket for fencing 300×55 mm, electro-galvanised

The gravel board bracket for fencing is a durable fitting used to securely connect concrete gravel boards to fence posts. Designed for gravel boards measuring 300 × 55 mm, it ensures a precise fit and a stable seating of the board regardless of ground and weather conditions.
The product is made of steel coated with electro-galvanised zinc, which gives it a characteristic silver, metallic appearance. The zinc coating effectively protects the steel against corrosion, moisture and weather conditions, ensuring many years of durability without the need for additional maintenance. The raw, industrial finish fits perfectly with the look of modern panel fences in the galvanised version.

Construction and installation
The bracket has a C-shaped profile in which the concrete gravel board sits. The external width of the profile is 57 mm, which allows a 55 mm thick board to be placed freely and securely, with a small installation clearance that makes seating easier. The built-in Ø 6 mm cross rod acts as a lock — it prevents the gravel board from slipping 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 bracket to be quickly screwed to the fence post. The elongated shape of the holes allows the position to be adjusted during installation, which significantly speeds up the installers' work and makes it easier to level the gravel board line on uneven ground. The flat base of the bracket protects the concrete board against mechanical damage during seating.
