A new name. Proven technology. Even more possibilities.

Höxter, 29 April 2026. The hallmark of our ATC system has always been its modular design – delivering maximum freedom of design and exceptional adaptability to any application.

With the introduction of the timing belt profiles HC and TC10, it became clear that the name ATC no longer fully reflected this diversity.

Previously marketed as the ATC system, it is now being relaunched under a new name: optibelt Modular Cleat System (MCS).

Advantages for you:

Polyurethane timing belts with insert system
Available from stock and ready for use in no time
Customised design and free choice of materials

The name says it all: maximum modularity and flexibility. Cleats and components can be freely positioned and adjusted on-site as required – making this a cost-effective alternative to welded profiles.
