All ClearSonic Acrylic Panel systems proudly feature our custom designed low-profile, heavy duty `mechanical lock' hinge. ClearSonic Acrylic Panels undergo an extra step in the manufacturing process that creates a `locking groove' on the long edge of the panels. This is achieved by the hard `tooth' on the hinge snapping into the groove for a superior, longer lasting hold.
Exceptions to this are the H-Channel (HCNL) and Base Channel (BASE) which attach to the smooth top and bottom of each panel and do not bend.
