Emcor Qualified Seismic Enclosures
Emcor seismic qualified enclosures are designed specifically to protect your equipment during seismic
events. To be seismically qualified, an enclosure must meet or exceed the Bellcore NEBS Zone 4 testing objectives and
requirements. Emcor has qualified three styles of enclosures to Telcordia GR-63 CORE Physical Protection.
Heavy Duty Seismic Enclosures
The heavy duty system utilizes Emcor's Military/Tempest Style 12 and 16 gauge frame construction. Side
panels are of a modified 16 gauge design. Each frame requires two (2) 1/4" (6.4) thick tie down brackets, one mounted front
and one rear. Test assembly consisted of the frame, which has a solid non-removable top and bottom panel area, two side panels,
a rear closure panel, eight equipment shelves and a custom flush lift-off front door with a 3 point T-handle latch system.
This design has been qualified to handle a load distribution of 800 pounds with the center of gravity at approximately 30”.
