KEEP THIS MANUAL Additional copies of this manual are available upon request at no charge. 2 Greenlee / A Textron Company 1.800.561.8187 www. . com [information@itm.com](information@itm.com) Bending—Handle Up 1. Mark the conduit. 2. Insert the conduit into the bender so that the arrow is aligned with the bending mark. 3. Place one foot on the bender as illustrated. Use heavy foot pressure on the bending shoe; maintain this pressure throughout the bend. 4. Look down the line of sight as illustrated. Stop bending when the pin is in line with the appropriate angle mark. Note: Overbend rigid conduit slightly to compensate for springback. Bending—Handle Down 3 1.800.561.8187 www. . com [information@itm.com](information@itm.com) Bending—Handle Down (cont’d) 1. Mark the conduit. 2. Insert the conduit into the bender so that the arrow is aligned with the bending mark. 3. Position the bender as shown, with your body as close to the benderas possible. 4. With the handle angled to prevent slipping, apply constant pressure against the conduit throughout the bend. 5. Bend until the edge of the conduit is in line with the degree scale as illustrated. Note: Overbend rigid conduit slightly to compensate for springback. Bending Tips: • Line up all bends in the same plane. • Bend 1/2" and 3/4" EMT with the handle down. • Bend 1" and 1-1/4" conduit with the handle up. • When bending with the handle up, work at a stairwell or loading dock so that previously made bends hang over the edge. Marking the Conduit for 90° Stubs 1. Measure the length of the required stub. 2. Measure and mark the stub length on the conduit. This is Mark A. 3. See the Deduct length shown on the bender. Subtract the Deduct length from Mark A and make a new mark. This is Mark B. 4. Align Mark B with the arrow on the bender and bend the conduit to 90° . 4 Greenlee / A Textron Company 1.800.561.8187 www. . com [information@itm.com](information@itm.com) Correcting Overbends If a stub-up is accidentally overbent, place the open end of the bender handle over the conduit and manipulate to desired angle. Back-to-Back 90° Stubs 1. Make the ﬁrst 90° stub

FAQs

What tools and conduit sizes are these SITE-RITE® hand benders intended for?

The aluminum SITE-RITE® and iron SITE-RITE® benders are intended to bend 1/2" through 1-1/4" EMT and 1/2" through 1" rigid and IMC conduit.

How should an operator align and bend when using the handle-up method?

Mark the conduit, insert it with the arrow aligned to the bending mark, apply heavy foot pressure on the bending shoe, and stop when the pin aligns with the appropriate angle mark. Rigid conduit should be slightly overbent to compensate for springback.

How do you determine an offset when rerouting around an obstruction?

An offset consists of two equal opposing bends. Select the offset angle by considering that steeper angles require more pulling force and shallower angles require more space, then use the Greenlee offset table values to work out the needed offset depth and center-to-center distance.
