Marks USA M9900F-48/32D 48" Fire Rated Rim Panic Device, Grade 1, Satin Stainless

The Marks USA M9900F-48/32D rim panic device is built for demanding commercial and institutional use where both panic-compliant egress and fire-rated performance are required. It is ANSI/BHMA A156.3 Grade 1 certified and UL listed for 3-hour fire door assemblies.

Designed for doors up to 48″ in width, this model is non-handed for simplified installation on either left- or right-swing doors. It features a heavy-gauge aluminum chassis with a stainless-steel touch bar and a full ¾″ stainless-steel dead-latch throw for reliable latching under load. The device includes an Allen-key (hex) dogging provision so that when desired, the push bar may be fixed in an unlocked state for high-traffic periods.

Finished in satin stainless steel (US 32D), the M9900F-48/32D combines rugged mechanics and architectural aesthetics. Finished with Marks USA’s Panic Protector™ end caps and backed by a lifetime mechanical warranty, this exit device is well suited for high-use doors in schools, hospitals, government buildings, retail centers and other environments where durability, fire listing and code compliance matter.
