Bent Knee Rail Brackets, Galvanised Steel Strap, 75 x 500mm or 100 x 500mm

Knee rail brackets are the galvanised steel straps used to fix the top rail of a knee rail fence to its upright posts. Knee rail fencing is the low post-and-rail barrier seen along village greens, verges, school grounds and park paths. Its posts are usually cut with a birdsmouth, a V-shaped notch, that the rail sits in. Each bracket here is a single flat steel strap bent once at a right angle. One leg wraps over the rail and the other runs down the face of the post, and both are nailed in place. The listed sizes are 75 x 500mm and 100 x 500mm. Brackets are sold individually. Grounds maintenance teams, councils and fencing contractors use them on new knee rail fences and to repair existing ones.

Why it works

A simple, strong strap fixing

A bent strap holds the rail down into the post from above and from the side, so the rail cannot lift out of its notch. There are no moving parts and nothing to loosen. Once nailed, the bracket stays put.

Galvanised for outdoor use

The brackets are galvanised to help them resist rust in all weathers. That matters on a fence that stands on open ground and is often wet.

Nailed, not bolted

The supplier states the brackets are fixed with 50mm nails. Fitting only needs a hammer, so it is quick to work along a long run of fence. Nails are not listed as included, so order them separately.

Know the sizing

The supplier lists the sizes as 75 x 500mm and 100 x 500mm, and the item names describe both as suitable for 100mm posts. The exact meaning of each dimension is not published for this line, so measure your rail and post before you order.

Where it's used

• Knee rail fences on village greens and verges
• Park, school and playing field boundaries
• Car park and driveway edges with timber rails
• Replacing rusted or missing brackets on existing fences

Specifications

Choosing the right option

Both sizes are the same price, finish and form. The choice comes down to your rail and post.

100 x 500mm suits fences built with 100mm timber, which is the most common section for knee rail fencing on public open spaces. Choose this size when your posts and rails are 100mm.

75 x 500mm is the narrower strap for lighter fences built with smaller timber. As the supplier's item names describe both sizes as suitable for 100mm posts, check the width of the rail the strap needs to cover before choosing.

You need one bracket per post where the top rail passes over it. Count the posts along the run, including end posts.

Installation, use & care

Sit the rail in the post notch first. Place the bracket so the bend sits on the top edge of the rail, with one leg on the top of the rail and the other down the post face. Nail through both legs with 50mm galvanised nails. Keep the strap tight to the timber as you nail so the rail cannot move. Check the brackets each year, especially after mowing work or vehicle knocks.

FAQ

Are nails included?

Nails are not listed as included. The supplier states the brackets are fixed with 50mm nails; use galvanised nails to match the bracket.

How many brackets do I need?

One per post where the rail crosses it. Count every post along the run.

Which size fits my fence?

The supplier describes both as suitable for 100mm posts. Choose 100 x 500mm for 100mm rails and measure before choosing 75 x 500mm.

Will they rust?

They are galvanised for outdoor use, which helps them resist rust. Damaged coating should be touched up.
