Product Description
1.8m x 75 x 75mm Knee Rail Fencing Top Rail
Timber Knee Rail Fencing is a sturdy and practical boundary solution made using the traditional birdsmouth jointing technique. Also known as Ascot or diamond fencing, the system uses horizontal timber rails secured to vertical posts to create a low-level boundary without obstructing visibility.
Please note: Timber knee rails do not meet the specifications for highway use.
Features & Applications
Knee Rail Fencing is designed to define boundaries at a low, knee-level height while maintaining clear sightlines. The birdsmouth joint features a precise notch in the end of the rail, allowing it to sit securely against the post for a strong and stable connection.
Made from durable, decay-resistant timber, the system is well suited to outdoor applications including car parks, pathways, walkways, parks and landscaped areas. It can help discourage access to grass and flower beds, define pedestrian routes and manage parking areas without creating a high-security barrier.
The system uses timber top rails and birdsmouth posts, secured with galvanised straps and nails. The fencing is supplied as a dig-in system, with the posts installed directly into the ground using post mix.
75 x 75mm Timber Top Rail
This 1.8m long timber top rail is manufactured from Tanalith E Green-treated timber and measures 1800mm x 75mm x 75mm. A 100 x 100mm version and a 3.6m long rail are also available, along with matching birdsmouth posts and galvanised straps.
The timber is supplied by a reputable UK sawmill and manufactured from Norway Spruce, predominantly sourced from North Wales. FSC certification is available upon request.
Tanalith E Green treatment helps protect the timber against decay and environmental exposure. Over time, the timber naturally changes from pale green to a honey colour before developing a silvery-grey appearance.
Installation
The knee rail system is designed for in-ground installation. Posts should be installed at 1.8m centres, with approximately half of the post length placed underground. Knee Rail Fencing is typically installed at 450mm or 600mm high.
We recommend using a minimum of 2 bags of Post Mix per post to provide a secure and stable installation.
For the 75 x 75mm top rail, choose either a V-style strap or Shoe-style strap. The Bishop's Hat-style strap is designed for the 100 x 100mm top rail, where the rail creates an overhang on the birdsmouth post.
Although the timber is pressure treated, applying additional wood treatment, particularly to cut ends, can provide further protection and help extend the timber's service life.
