Product Overview
The Chief LWM3X1UM Fusion large modular wall mount builds a 3x1 menu board for digital signage in quick-service restaurants, retail, and commercial lobbies. Its modular extrusions ship with installation connectors in compact packaging for easier handling and stocking, then assemble into a single aligned row on the wall. ControlZone micro-height adjustment and Centris tilt give installers precise leveling and glare control after the displays are hung. The mount accommodates 40" to 55" screens in portrait or landscape.
Product Description

The LWM3X1UM is part of the Chief Fusion menu board wall mount line and offers precise display positioning with flexible adjustments. A horizontal extrusion with depth adjustment aligns screens quickly even on irregular mounting surfaces and allows easy access behind the displays for servicing. The modular extrusions ship shorter, with installation connectors, so they fit on standard-sized pallets and are easier to ship, handle, and stock than fixed-length rails. ControlZone micro-height adjustment fine-tunes leveling after installation, and Centris tilt between +0 and -20 degrees manages viewing angle and glare. Tool-free screen engagement simplifies installation and service. The platform supports portrait and landscape orientations for 2x1 and 3x1 configurations and landscape for 4x1 and 5x1 configurations, accommodating 40" to 55" screens. Optional padlock security protects displays in public-facing locations, and a full line of accessories works across Fusion wall, ceiling, and freestanding lines.
