One shape, two applications
A purpose-built equipment plane
ATL4 and ATL5 provide a flat surface thick enough to support mounted accessories without disrupting the clean lines of an Atlantic Towers® structure.
Custom hardtop integration
The extrusion is welded into the hardtop frame, normally running the full centerline length directly beneath the fiberglass top, to support equipment installed above.
Concealed rigging
Hardware disappears after installation
On a custom hardtop, the extrusion creates a protected route for mounting hardware and electrical runs. The result is serviceable during rigging and visually quiet when the work is complete.
- 01
Mount the equipment
Accessory equipment is secured to the extrusion's substantial flat surface.
- 02
Route wiring and cables
Mounting bolts, wiring, and cables are placed inside the open channel instead of remaining exposed below the structure.
- 03
Close the channel
UV-resistant plastic cover panels snap back into position to conceal the completed rigging.
Plan the equipment before fabrication
Build the mounting and wiring path into the structure
