constructed of the materials and in the manner described within the individual U300, U400
or V400 Series Wall or Partition Designs in the UL Fire Resistance Directory and shall
incorporate the following construction features:

studs to consist of nom 2 by 4 in. [51 by 102 mm] lumber spaced max 16 in. [406 mm]
OC. Steel studs to be min 1-5/8 in. [41 mm] wide and spaced max 24 in. [610 mm] OC.
B. Gypsum Board* – Thickness, type, number of layers and fasteners as specified in the
individual Wall and Partition Design. Diam of opening shall be 2-1/4 in. [57 mm] and 4-3/4
in. [121 mm] for the nom 2 in. [51 mm] and 4 in. [102 mm] sleeves (Item 2), respectively.
The hourly F Rating of the firestop system is dependent upon the hourly rating of the wall
in which it is installed.
2. Metallic Sleeve – Nom 2 in. [51 mm] or 4 in. [102 mm] diam electrical metallic tubing (EMT),
dependent on the size of the firestop device (Item 4). The sleeve is to extend a min 7/8 in. to

G. Max 8/C 12 AWG (or smaller) copper conductor steel Metal-Clad or Armored-Clad cable.
The hourly T Rating of the firestop system is equal to the F Rating when no cable fill is used
or when cables A or B are used. The hourly T Rating is equal to the F Rating up to 3 hr when
cable C is used. The hourly T Rating is 1 hr when cable D is installed in 2, 3 or 4 hr rated
walls, 1/2 hr in 1 hr rated walls. The hourly T Rating is 1 hr when cable E is installed in 4 hr
rated walls and 0 hr in 1, 2 or 3 hr rated walls. The hourly T Rating is 3/4 hr when cable F is
installed in 2, 3 or 4 hr rated walls, 0 hr in 1 hr rated walls. The hourly T Rating is 1/4 hr
when cable G is installed in 2, 3 or 4 hr rated walls, 0 hr in 1 hr rated walls.
The L Rating at ambient and 400°F with no cable fill is 3.7 CFM and 2.1 CFM, respectively.
The L Rating at ambient and 400°F with cable fill is 4.6 CFM and 2.0 CFM, respectively.

A. Firestop Device* – Heat Shield – The heat shield shall be installed in accordance with
the accompanying installation instructions. Device to be installed around the outside of the
EMT sleeve both sides of wall. – THE WIREMOLD CO. – FS2RHS, FS4RHS
B. Firestop Device* – Device to be installed in accordance with the accompanying
installation instructions. Device to be installed and secured to the heat shield (Item 4A) at
the end of the EMT sleeve on both sides of wall. – THE WIREMOLD CO. - FS2R
