FeaturesYour IDEAL Bender has engineered features which include:1.2.3.4.5.ArrowTo be used with stub, offset and outer marks of saddlebends.Rim NotchLocates the center of a saddle bend.Star-PointIndicates the back of a 90 bend.Degree ScaleFor offsets, saddles and those special situations.A ChoiceHigh strength ductile iron or light weight aluminum.The above are features that lead to perfectly predictable and repeatable bends.InstructionsBend conduit with skill and professionalism. Take the guesswork out of bending.Steps to RememberStep 1. Measure your job.Step 2. Mark you conduit using the recommended tables.Step 3. Use your bender’s engineered marks.Note: Reference to the above Steps 1, 2, and 3 will be madethroughout this booklet.–1–

Don’t Forget When bending on the floor, pin the conduit to the floor. Useheavy foot pressure. When bending in the air, exert pressure as close to your bodyas possible. In case you overbend, use theback pusher or the expandedend of the bender handle tostraighten your conduit tofit the job.How to Bend a StubThe stub is the most common bend. Note that your bender ismarked with the “take-up” of the arc of the bender shoe.Example:Consider making a 14” stub, using a 3/4” EMT conduit.Step 1.Step 2.Step 3.The IDEAL bender indicates stubs 6” to . Simplysubtract the take-up, or 6”, from the finished stubheight. In this case 14” minus 6” 8”.Mark the conduit 8” from the end.Line up the Arrow on the bender with the mark on theconduit and bend to 90 .Remember: Heavy Foot pressure is critical to keep the EMT inthe bender groove and to prevent kinked conduit.–2–

How to Make Back-To-Back BendsA back-to-back bend produces a “U” shape in a single length ofconduit. Use the same technique for a conduit run across the flooror ceiling which turns up or down a wall.Example:Step 1. After the first 90 bend has been made, measure tothe point where the back of the second bend is to be, “B”.Step 2. Measure and mark your conduit the same distance,mark “B”.Step 3. Align the mark on the conduit with the Star-Point onthe bender and bend to 90 .Star-Point on bender must be referenced for accurate bends.–3–

How to make an Offset BendThe offset bend is used when an obstruction requires a change inthe conduit’s plane.Before making an offset bend, you must choose the most appropriate angles for the offset. Keep in mind that shallow bendsmake for easier wire pulling, steeper bends conserve space.You must also consider that the conduit shrinks due to the detour.Remember to ignore the shrink when working away from theobstruction, but be sure to consider it when working into it.Example:Step 1. Measure the distance from the last coupling to theobstruction.Step 2. Add the “shrink amount” from the table on page 5 tothe measured distance and make your first mark. Yoursecond mark will be placed at the “distance betweenbends.” (Refer to table on page 5.)Step 3. Align the Arrow with the first mark and using theDegree Scale bend to the chosen angle. Slide downthe conduit and rotate conduit 180 , align the Arrowand bend as illustrated.Bend offsets in the air.Remember to keep your bodypressure close to the bender.First Bend–4–

It is used most often when another pipeis encountered.Most common is a 45 center bend and two 22-1/2 outer bends,but you can use a 60 center bend and two 30 bends.–5–

Important: Use the same calculation for either set of angles.Example:Step 1. You encounter a 3” O.D. pipe 4 feet from the lastcoupling. The formula shown in the chart belowindicates that for each inch of outside diameter of theobstruction, you must move your center mark ahead3/16” per inch of obstruction height and make yourouter marks 2-1/2” per inch of obstruction heightfrom the center mark.Step 2. The following table gives the actual mark spacings.In this example, the center mark is moved ahead9/16” to 48-9/16”. The outer marks are 7-1/2” fromthe center mark, or 41-1/16” and 56-1/16”. Mark youconduit at these points.If ObstructionisMove Your CenterMark AheadMake Outside MarksFrom Center 8”15”Step 3.(A) Align the center mark with theRim Notch and bend to 45 .(B) Do not remove the conduitfrom the bender. Slide thebender down to the next markand line up with the Arrow.Bend to 22-1/2 as indicated.(C) Remove and reverse theconduit and locate the otherremaining mark at the Arrow.Bend to 22-1/2 as indicated.–6–

CAUTIONBe sure to line up all bends to be in the same plane.HickeysHickeys require a different approach to bending. It is not a fixedradious device but rather one that requires several movementsper bend. The hickey can give you the advantage of producingbends with a very tight radius.Order InformationConduitSizeDuctileIron 21Handles3/4” IPS 38” Long ExpandedExtra High Strength Handle1” IPS 44” Long Extra HighStrength Handle1-1/4” IPS 54” Long ExtraHigh Strength Handle74-01974-02074-021The IDEAL bender line gives you the engineering design, indicator marks anddurability to bend conduit with ease and confidence.IDEAL INDUSTRIES, INC.Sycamore, IL 60178, U.S.A.800-435-0705 Customer Assistancewww.idealindustries.comND 1534-4
