The Light Duty System utilizes Emcor's standard 10 Series 14 and 16 gauge frame construction and side panels of a modified 16 gauge heavy duty design. Each frame requires two (2) 1/4" (6.4) thick tie down brackets, one mounted front and one rear. The qualified assembly consisted of the frame, two (2) side panels, four (4) equipment shelves and a front door. This design is qualified to handle a load distribution of 400 pounds at a designated center of gravity.

Light Duty Specifications  2 Panel Widths:  19-1/16" (484.2)    24-1/16" (611.2)  3 Depths:  26-5/16" (668.3)    31-9/16" (801.7)    36-7/8" (936.6) 9 Vertical Opening Heights (Range):  26-1/4" (666.8) to 78-3/4" (2000.3)

The Medium Duty System also utilizes the same frame as the light duty system with additional back-up welds and frame gussets. Each frame requires two (2) 1/4" (6.4) tie down brackets. This test assembly was equipped the same as the light duty unit except for the front being open without a door. This design qualified at a 600 pound load distribution level at a specific center of gravity. For more information, please see the latest seismic qualification report (1.3 MB, PDF).

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 at a specific center of gravity.

NOTE: Emcor has tested and qualified various single bay cabinet designs to the Telecordia GR-63-CORE, Zone 4 seismic specification. Modifications made to the tested cabinet configuration, its weight load distribution, the accessories utilized or the integration of frames into multiple cabinet bays may affect performance. A formal test report, load distribution criteria and engineering assistance is available by contacting Emcor direct. Please contact Emcor for more information on seismic enclosures.
