RUGGED HANDHELDS

Juniper Systems Allegro 3 Screen Protector

The Juniper Systems Allegro 3 is a rugged handheld computer with a 4.2" display, 640x480 (VGA) resolution. Rugged handhelds live with drops, gloved input, and scanner-heavy workflows. Fleet buyers usually start from the manufacturer's own film part number when one exists, then compare custom-cut options for quantity pricing. Screen dimensions are sourced from manufacturer documentation; protector cut dimensions are confirmed with the supplier before production.

Screen dimensions are the device’s active display area, not protector cut dimensions. Cut sizes depend on bezel geometry and adhesive design and are confirmed with the supplier before any production run. Housing dimensions are the overall device body, not the screen. Aspect ratio and pixel density are derived from the sourced values above.
