JORDAHL® anchor channels type JXA W are used for connections to concrete and provide enhanced load resistance in the longitudinal direction of the channel. The hot-rolled toothed profile of the cast in channel range enables long-term dynamic load performance resisting fatigue and explosive events. JORDAHL® JXA W cast in anchor channels are evaluated in assessment documents UKTA - 0836-22/6149 and ETA/09-0338.

The teeth on the inner surface of the channel lips interlock with teeth on the connecting T-bolts providing a secure mechanical interface for the resistance of longitudinal shear loads. This feature enables the support of high gravity loads for applications where height adjustment is important. It is also useful for the resistance of loads that might be acting in two or three planes concurrently such as seismic/explosive events, or wind loads.

Design resistance of up to 37.8 kN per connection is available.

Standard T-bolt diameters range from M10 to M24.

Features and benefits: `

Reliable and versatile fastening of high loads acting in all directions.
Simple connection adjustment to accommodate building tolerances.
No drilling of concrete or site welding, so reducing site hazards such as silica dust, noise, vibrating tools and fire risks.
Faster connections with simple hand tools reducing site energy requirements.
Connections close to concrete edges are possible.
Easy to replace or re-position connected components.
Resistant to fatigue, seismic activities, explosions.
High tightening torques.
Approved fire resistance performance.
Evaluated in assessment documents UKTA - 0836-22/6149 and ETA/09-0338.
Accommodates highly cracked concrete in damaged structures (JXA-PC).
