For use in rolling stock applications

The most versatile, compact and lightest design of its kind on the market

PMA presents the new generation of modular support system for conduits and cables which redefine the state-of-the-art for rolling stock applications in terms of ease of installation, flexibility, lightness, durability and compactness.

Lightweight, compact with high impact resistance
PMA TRUST™ modular support system is a lightweight, compact solution with high impact resistance. Thanks to the new design, external dimensions are reduced the very minimum and internal spacing between adjoining conduits is very small. The system is specifically designed for use in railway vehicle construction and other applications where fixation of parallel running conduits and cables is required.

Save up to 30% of installation time
Thanks to the modular system, up to 30% of installation time can be saved. Each element can hold different combinations of both, conduits and cables in various sizes. Multiple conduits and cable in various sizes can be clamped in one element which is then secured with only two screws.

Quick and user friendly installation 
The new modular support system offers total flexibility in terms of installation complying with all kinds of installation requirements. Each element can host different combinations of both conduits and cables, in various and different sizes, so that cable routing is made easy regardless of its complexity. Furthermore the fixation of the modular support system can be done with different techniques: on a C-rail, pre-assembled, stacked or upside-down.

Conduit rotation possible, preventing torsion
The single rib fixation provides a high axial retention force and compatibility with both coarse and fine profile conduits. Conduits are able to rotate in the fixation preventing torsion stresses to conduits in moving systems.
The PMA TRUST™ modular support system is compatible with all PMAFLEX, PMAFLEX Pro and PMA Smart Line conduits.
Your key benefits with the PMA TRUST™ modular support system
