EVO GRIP™ – Variable High-Load Connector
Standard and Solo – EVO GRIP high-load connector for increased strength in timber construction
With the EVO GRIP high-load connector, KNAPP offers a powerful solution for main beam, secondary beam and column connections in modern timber construction.
The variable connector covers medium to extremely high loads from 55 kN to 550 kN and is suitable for timber-to-timber, timber-to-steel and timber-to-concrete connections.
Flexible connections in timber-timber, timber-steel and timber-concrete
The width and height of the connector, suitable for timber-timber, timber-concrete and timber-steel connections, can be parametrically adjusted to match beam widths, load requirements and fire protection demands.
Thanks to the increased load capacity, smaller fasteners can be used, enabling greater timber cover for fire protection while providing more flexibility in designing beam cross-sections.
Standard variant – compact hook-in solution for extreme loads
The Standard variant of EVO GRIP serves as a conventional hook-in connection for high and extreme loads. It features a short hook-in path and sufficient installation tolerance for easy mounting.
Additionally, this variant includes an integrated lateral load-resisting feature and allows the use of comparatively smaller connector sizes despite its high load-bearing capacity.
This enables efficient and slender timber structures.
Solo variant – articulated connection for deep beams
For deep beams or beams experiencing significant deflection under load, EVO GRIP is available as a Solo variant with articulated behaviour.
Thanks to the optimal screw arrangement, additional transverse reinforcement can often be omitted.
The Solo variant provides increased rotational freedom at the connection point and is ideal for demanding engineered timber structures.
- higher load-bearing capacity for aesthetic, material-efficient designs
- Solo variant with articulated connection available for deep beams
- Standard variant available for extreme loads
- improved fire protection achievable
- flexible dimensions
- comparatively smaller connector sizes possible with the same load-bearing capacity
- variable screw pattern
- short hook-in paths with sufficient installation tolerance
Proven heavy-load connector in engineered timber construction
The EVO GRIP has already been successfully used as a wall-to-floor connector at the Lignotrend sawmill in Ibach, where it demonstrated its performance under real operating conditions.
This makes EVO GRIP the ideal choice for load-bearing connections in engineered timber construction, where high load capacity, flexibility and cost efficiency are required.
EVO GRIP – Load Capacity Table (Excel)
Functions of the Excel Tool
- Selection of different inclined and horizontal screw lengths for EVO GRIP
- Input of installation heights in the main and secondary beams
- Automatic output of characteristic load-bearing capacities and design-relevant values
- Adjustable safety factors — since National Annexes (NAD) vary by country for timber, steel and aluminium, these values can be adapted to the project requirements
