The 2310ME, 4310ME and 4410ME Sentronic closers provide adjustable hold-open points for fire and smoke barrier doors. The closers are UL listed for metal smoke barriers or labeled fire doors. They also meet ANSI/BHMA A156.15 and NFPA 101 Life Safety Code standards. Each closer is backed by a 2-year limited warranty, offers optional plated finishes and integrates with existing fire and life safety systems, minimizing danger to life and property under fire conditions.

The 2310ME, 4310ME and 4410ME Series function as full rack-and-pinion door closers when hold-open is not engaged or the electrical current is interrupted. The finishes, cylinder functions and installation accessories meet virtually all life and safety requirements.
