Keeps forcefully inserted ensures a straight conduit run with no sagging over extreme lengths conduit from breaking through the opposite side of the coupling, while not interfering • Chamfered entry provides lead-in with the pulling of conductors for conduit insertion Dependable Pipe Stop Heavy-Duty Thick Steel Body/Glands with Continuous Threading • 360° groove traveling the circumference ensures that conduit forcefully inserted • True hexagonal shape. The non-circular won’t break through to the opposite side design has actual flats for gripping power of the fitting. Also, it does not exceed using hand or tool force thickness of EMT and prevents interference with pulling conductors Extra-Thick Electro-Plated Zinc Finish Extra-Large Head Tri-Drive Set Screw • Ensures corrosion resistance while the clear • Accommodates Phillips, slotted chromate coating gives the fittings their and square drives quality shine and luster Enhanced Locknut Construction • Heavy-duty turned sharp teeth, double-threaded United States Technical Services www.tnb.com Tel: 901.252.8000 Tel: 888.862.3289 800.816.7809 E-520 Fax: 901.252.1354 ® Conduit & Fittings — Steel City Commercial Fittings ® Conduit & Fittings — Steel City Commercial Fittings Overview ® Here’s How the Steel City Catalog Number System Works Easy-to-identify alphabetical prefixes: BG – Bushings, Grounding SH – Service Entrance Fitting 2nd Digit — Method BI – Bushings, Insulated SL – Service Ells 1 = Compression BL – Blanks SR – Sealing Rings 2 = Set Screw BR – Rigid Spacer SS – Stainless Steel 3 = Other BS – Box Spacer LS – Locknut, Sealing 3rd/4th Digit — Size BT – Thinwall Spacer TC – Thinwall Connectors 3 0 = ⁄8" BU – Bushings TK – Thinwall Couplings 1 1 = ⁄2" CB – Clamp Back TL – Thinwall Elbow 3 2 = ⁄4" CP – Cable Protector TO – Thinwall Offset 3 = 1" EK – 3-Piece Coupling TS – Thinwall Strap 1 4 = 1 ⁄4" FA – Fire Alarm TX – Thinwall to Flexible Metallic Conduit Fitting 1 5 = 1 ⁄2" GA – Ground Clamp (Armored Ground Wire) UC – Utility Connector 6 = 2" GC – Ground Clamp USA – Made in USA 1 7 = 2 ⁄2" H – Hub WA – Washer 8 = 3" HA – Heavywall Adapter XC – Armored Cable or Flexible Metallic Conduit Connector 1 9 = 3 ⁄2" HC – Heavywall Connector XK – Armored Cable or Flexible Metallic Conduit Coupling 10 = 4" HK – Heavywall Coupling 1st Digit — Material 11 = 5" HL – Heavywall Elbow 1 = Steel 12 = 6" HO – Heavywall Offset 2 = Die Cast HS – Heavywall Strap 3 = Combination Steel and Die Cast LG – Locknut, Grounding A few examples of the three-digit identification 4 = Malleable LN – Locknut system for thinwall fittings are: 5 = Plastic 1 LT – Liquidtight TK-111A: ⁄2" steel, compression-type coupling 6 = Aluminum NC – Non-Metallic Sheathed Cable Connector 1 7 = Steel Insulated TC-714A: 1 ⁄4" steel insulated compression-type connector NS – Non-Metallic Sheathed Cable Strap 8 = Die Cast Insulated 3 TC-822SC: ⁄4" die-cast, insulated, set-screw type connector RB – Reducing Bushings 9 = Malleable Insulated RT – Raintight United States Technical Services www.tnb.com Tel: 901.252.8000 Tel: 888.862.3289 800.816.7809 E-521 Fax: 901.252.1354 Electrical Metallic Tubing (EMT) Fittings Ideal for use in Recovery Act projects requiring MADE IN USA components!
