Kit Set Up: Our kits are based on having existing concrete posts and a 300mm gravel board. For example, 6ft fence boards cover 1.5m, and the existing gravel board provides the remaining 300mm to achieve the final 6ft height.
Fence Slats: Fence boards are 1.83m in length to ensure all existing concrete post widths are covered. Cutting may be required on some occasions.

Expert Advice & Guides for Slatted Fence Panels
A Word from Our Expert, Allan Jeffrey BSc. Eng. (Hons), Composite Materials Specialist, Environmentalist, and CEO of Ultra Decking:
We saw how popular the ‘slatted’ look was becoming in UK gardens, but our customers kept asking one question: ‘Can you make a slatted panel for our existing concrete posts?’. We listened. By engineering the enhancements from our popular slatted cladding into a new fence system, we created what we believe is the UK’s first affordable solution for this. It’s a design that delivers a luxurious, authentic wood look without the high maintenance—the exact solution our customers asked for.”

No problem! All our existing concrete kits are calculated based on having a 300mm existing gravel board, or all you will need to do is order two extra composite boards on their own to ensure it fits.
