Thyrm VariArc-VS™ Helmet Mount

A universal helmet mount and multi-directional indexing: The VariArc-VS shines light right where you need it.

The VariArc-VS™ helmet mount provides a full-featured, universal mounting solution for headborne illumination. The locking teeth are biased to the forward position, keeping your light aligned for the most critical uses, but with a firm twist, the VariArc-VS mount unlocks and rotates through 8 additional lower-force index points for administrative tasks and diffused lighting options. Its small footprint and low profile keep things tidy. The VariArc-VS includes both a Picatinny rail and a Scout light mount, allowing for maximum compatibility with visible and IR lights. The VariArc-VS is built to remain fully functional through extreme temperatures, dirt, dust, sand, water, drops on concrete, and rough handling.

The VariArc-VS Helmet Mount:
• Has high-strength hook Velcro® that provides secure attachment with a space-efficient footprint
• Includes both Picatinny rail and direct Scout light mounts
• Positively locks in the forward index position
• Directs light through 360 degrees, with 8 additional lower-force index positions
• Works in vertical positions for umbrella lighting rooms, canopy illumination, and IR strobe signaling
• Can be used in downward angles for admin & task lighting
• Has an angled pivot, allowing the user to optimize mounting for a lower profile or a more vertical rotation plane
• Has large openings on both ends of the base, allowing for retention cords including 550 paracord
• Has durable, reinforced polymer construction with steel hardware
• Is designed and made in the USA
