1 n enterprise of United McGill orporation - Founded in 1951 One Mission Park Groveport, Ohio / , Fax: 614/ marketing@mcgillairflow.com Web site: Single-Wall Round UNI-GSKET Fitting and Related Product Dimensions McGill irflow orporation offers UNI-GSKET fittings featuring an EPDM rubber gasket that provides a reliable, airtight seal. Testing has shown that UNI-GSKET fittings meet or exceed SMN 1 lass 3 for leakage at - 20 in. wg to + 20 in. wg. The galvanized steel construction 5 meets SMN s 10 in. wg positive pressure standards 2. UNI-GSKET fittings are compatible and available with all of McGill irflow s round, single-wall duct types in 1-inch increments for 3- through 12-inch diameters and in 2-inch increments in 14- through 24-inch diameters.

See the Single-Wall and Single-Wall Lined, Round Duct and Fittings Dimensions booklet for the full range of available sizes. 3 Standard lengths of round UNI-SEL and UNI-RIB duct are 10, 12, and 20 feet; longer lengths are available on special order. 4 The rating of +10 in. wg for Spiral Lockseam with Standing Rib Duct is based on McGill irflow laboratory testing. 5 vailable in galvanized, paintable galvanized, and SilverGuard TM precoated ductwork with antimicrobial McGill irflow orporation

3 Dimensioning: ll alphanumeric dimensions are in inches; all angles are in degrees. - Main barrel inlet diameter B - Main barrel outlet diameter or D - Branch tap diameter (Note: On tee and lateral fittings with two taps, is the branch closest to the inlet of the fitting. On cross fittings, is the larger of the two taps.) R - enterline radius S - Slip-fit dimension of a fitting F,, J, L, Q, - Miscellaneous dimensions (refer to specific drawings), Z, m, α or Φ - ngular measurements (refer to specific drawings) # - Number of elbow gores Designations: McGill irflow uses a designation system that simplifies product nomenclature. ed fitting products can be accurately identified using a concise alphanumeric designator. Each character in the designation defines a characteristic of the product. Example: SR0PT refers to a single-wall (S), round (R), 10 in. wg positive pressure class (0), straight tee tap (PT). 1 st haracter: Wall onfiguration - SR0PT S = Single-wall 2 nd haracter: Shape - SR0PT R = Round 3 rd haracter: Pressure lass - SR0PT 0 = +4 to +10 in. wg S = standard gauge of product type 4 th and Subsequent haracters: Product Type - SR0PT PT = Straight Tee Tap (90 E branch tap) 3

4 General Notes: Dimensions other than diameters are held within a ± 1/4-inch tolerance. em Bead Unless ordered otherwise, a given diameter of single-wall, round fittings is sized to slip fit into the same diameter of single-wall, round duct. Where: S = 1 ½ inches for diameters # 8 inches S = 1 e inches for diameters $ 9 inches S Galvanized steel meets STM Numbers 653 and 924 Unless ordered otherwise, the branch taps of laterals, crosses, lateral crosses and Y-branches are installed at standard angles to the fittings' bodies and to each other, as shown in the following drawings: LTERL STRIGT 90 E ROSS Y - BRN For all: Laterals - standard = 45 E Straight rosses - standard = 90 E, Φ standard = 180 E Lateral rosses - standard = 45 E, Φ standard = 180 E Y - Branch - standard = 90 E Note: Φ is the included angle between taps as viewed in cross section (standard is 180 E ). When ordering fittings of nonstandard Φ, please include an end view sketch. 4

5 Installation: Make sure the end of the duct or gasketed fitting is not damaged. Insert the gasketed fitting into the spiral duct up to the fitting bead. Turning the fitting slightly as it is inserted may make installation easier. Secure the fitting to the duct with self-tapping screws uniformly located around the circumference according to SMN recommendations. Use at least one screw for every 15 inches of circumference with a minimum of three screws for 14-inch or smaller diameters. The following chart illustrates some typical gasketed assemblies: oupling Reducer Elbow The following figure illustrates gasketed fittings assembled to ductwork with a manifolded tap: 5
