Details

The Catnic Arch Centre is a specialist PVC-u arch unit designed for use over openings in external cavity walls, ideal for builders and contractors working on traditional and timber frame projects. Offering reliable permanent centring for brick arch construction, this component ensures precision and durability on site. Please note the product is supplied wrapped for protection and must be unwrapped prior to installation.

It is commonly used alongside Catnic lintels and suits a range of structural openings where a neat, professional finish is required.
