The patented Topclamp connector
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.
A demonstration of the connector can be found in the video below.

A wide variety of joints, profiles and accessories are available, you can find an overview and price in the price list.
Custom joints and components are also possible. Special angles, additional holes etc. can be made on request.
