Marks USA Locks Approved for Hurricane Zone

Feb. 13, 2017

Marks USA, a division of Napco Security Technologies, Inc. announces that its cylindrical and mortise locks have received a Notice of Acceptance (NOA) from the Miami-Dade County Regulatory and Economic Resources Board and Code Administration Division, and have been tested to comply with Florida Building Code, including the High Velocity Hurricane Zone – known to be some of the toughest standards in the country.

The following Marks USA products are approved as lockset hardware devices for use on commercial steel doors, in the county and, the state, i.e., other areas where allowed by the AHJ (authority having jurisdiction): 95-Series Survivor™ Grade 1 Cylindrical Locksets, 175-Series Economy Locksets, 5-Series Nova™ Mortise Locksets and 130-Series Defender™ Locksets.

While Marks has long promoted the fact that many of its popular products have been proven to meet or exceed tough standards for durability, by as much as  three times, for as many as 3 million cycles, i.e., BHMA ANSI Grade 1 Rating,156.2, Bill Sporre, Marks VP Global Sales & Marketing  said, “It’s gratifying to see that our locks stood up to these tough NOA tests for large missile impact, air filtration, cyclic wind pressure loading, forced entry and static pressure.  I tell customers all the time, ours is the last lock they’ll need to put on a door.”  Marks also stands behind its products with a Lifetime Mechanical Warranty, an industry first.

The Marks USA NOA certificate, No. 16-3016.03, is available online at or
