Magswitch AR70 NAAMS – 8140681

Equivalent to the AR Classic series tools, the NAAMS variant brings repeatable mounting to the table. A dual 4-hole NAAMS pattern makes this tool easy to design around. This is the best option for use without a mounting bracket. As with the AR Classic series, pole shoes are required for use and improve performance on irregular surfaces.

Feature & Benefits
• Compact single magnet design
• Fast MTTR with NAAMS mounting
