The SHERPA CLT connector is a coupling element for angle joints, t-joints and longitudinal joints, wall to ceiling connections, as
well as ceiling joints.
Optimised for three-layer and five-layer cross-laminated timber elements, the SHERPA CLT connector can be mounted flush in
solid wood or glulam already in the preinstallation phase, enabling ready-for-installation delivery to the construction site.
The CLT connector must be milled flush into cross laminated timber or glulam. The load capacity according to ETA can only be
guaranteed when using SHERPA special screws.
