Product Overview:
Birdsmouth Galvanised Post Straps is a steel fixing used to secure a diamond-shaped timber rail within the V-shaped notch of a Birdsmouth post. It is an essential component of traditional knee-rail fencing, holding the rail firmly at each support point while maintaining the open appearance of low-level boundary fencing. The strap is formed around the rail and secured to the timber using suitable exterior-grade fixings.

Its galvanised finish provides resistance to rust and weathering, making the strap suitable for prolonged outdoor use in commercial, agricultural and domestic locations. Contractors and landscapers choose this fixing because it creates a simple, reliable connection without complex brackets or specialist installation methods. Correctly fitted, it reduces rail movement and helps maintain the stability of the completed fence. It is particularly useful for defining car parks, pathways, landscaped areas and site boundaries where full-height fencing is unnecessary.

Frequently Asked Questions:
Q. What type of fencing is this strap designed for?
A. It is designed for Birdsmouth or knee-rail fencing, where a diamond-shaped timber rail sits within the V-shaped notch at the top of the post.

Q. How is the strap fitted?
A. Position the rail within the Birdsmouth post, form the strap securely around the rail and fasten it through the pre-drilled holes using suitable exterior-grade fixings.

Q. What fixings should be used?
A. Use suitably sized galvanised or stainless-steel nails or exterior-grade timber screws appropriate for the post, rail and installation conditions.

Q. Will the strap fit every Birdsmouth rail?
A. Birdsmouth posts and rails are available in different sizes. Check the strap dimensions against the selected rail and post before ordering.

Q. Does the galvanised finish require maintenance?
A. The galvanised coating provides corrosion protection under normal outdoor conditions. Periodic inspection is recommended in coastal, industrial or highly exposed locations.

Q. Does the strap support the rail by itself?
A. No. The rail must be seated correctly within the post’s V-shaped notch. The strap retains the rail and reinforces the connection.
