Product Description
LCN 4511 with Extra Duty Arm with AVB in Aluminum
The LCN 4511 is the top-of-line high-security surface closer. Where the 4211 gives you security-grade closing, the 4511 adds even more tamper resistance and control options for maximum-security environments. Ships in Aluminum finish — the standard architectural finish that blends with most commercial door frames.
Pro-Tip from Our Locksmiths: On the 4511, every fastener is concealed once the cover is installed. If you're working in a facility where inmates can access screws, this is the one you spec. The 4211 covers most security needs, but the 4511 is for the highest-risk openings.
