Every project you build with Unistrut requires channel AND fittings, but in many instances, folks get overwhelmed by the number of fittings choices.
This post offers some basic information on 90 degree Unistrut fittings and offers links to product detail pages where you can learn more about a particular part number and request a quote.
Whether you need a basic, angled two-hole fitting, a bracket with holes and slots, or a gusseted right angle fitting for added strength, the Unistrut catalog contains a diverse and varied family of 90 degree fittings designed to make short work of your project. Each of the pages on our website dedicated to Unistrut angular fittings contains detailed product information on finishes, materials, sizes, and ordering information. You’ll also find a submittal PDF for each part number.
Below, are some quick additional pointers on 1-5/8″ compatible 90 degree fittings for handy reference:
Fittings, unless noted, are made from hot-rolled, pickled and oiled steel plates, bar, strip or coil, and conform to one or more of the following specifications: ASTM specifications A575, A576, A635, A1011 SS GR 33, A1011 HSLAS GR 45 or A36. All fittings meet or exceed physical properties of ASTM A1011 GR 33. The pickling of the steel produces a smooth surface free from scale. Many fittings are also available in stainless steel, aluminum and fiberglass.
All parts drawings in the catalog and on our website illustrate only one application of each fitting. In most cases many other applications are possible. The channels shown in the illustrations are P1000, 15⁄8″ square, except where noted otherwise. All 9⁄16″ diameter holes use 1⁄2″ x 15⁄16″ hex head cap screws and 1⁄2″ nuts – P1010, P3010, P4010 or P5510 – depending on the channel used. Nuts and bolts are not included with the fitting and must be ordered separately.
Imperial dimensions illustrated in the catalog and on the
Design load data, where shown, is based on the ultimate strength of the connection with a safety factor of 2.5, unless otherwise noted.
