Fixing near an edge can split concrete, brick or timber. Minimum distances depend on the product, base and force direction.
Method basis: Rigips/Knauf system guidance and Fischer/Hilti fixing-selection principles. Final parameters always come from the selected product data.
How to plan the installation
Measure from the hole centre to the free edge and between centres, including corners and joints.
Common mistake
Do not shift a point by a few millimetres without rechecking the technical data.
Pre-start check
- Was the structural base identified rather than only the finish?
- Does the weight include contents and projection?
- Were services, edges and minimum spacing checked?
- Does the product data permit the base, direction and environment?
