Topclamp Original
Patented frame constructions systems, designed and developed by Dutch Innovation Systems.
Topclamp Original is a unique system consisting of aluminium joints, square profiles and connectors. Our patented connector is a mechanism that, when inserted into the joint and tightened, pulls the profile tightly against the joint for a strong, flush connection with a single screw.
Years of development went into creating the Topclamp connector.
By turning a single screw our connector makes a strong, flush connection between the joint and profile.
The connector is specially designed for ease of use and to be reusable, many times over for the ideal frame construction system.
Topclamp Wood
Topclamp Wood are high quality joints for square wooden beams.
The joints are purposely designed with ease of use in mind. The design of the joints make the positioning self-evident and angles easy.
Extra strong stainless steel C1 selfdrilling torx screws are included.
