Heavy foot pressure is critical to keep the emt in the bender groove and to prevent kinked conduit. Web learn how to bend conduit to any configuration, not merely the common bends. When appearance counts, concentric bends may be the only way to go. Web place the arrow on the bender handle on the 30” mark (distance needed for 90 minus the deduct). This is known as the developed length.
Reverse bender and repeat at point (y). Even the “multiplier” and “deduct” figures are usually stamped onto the bender device. This is known as the developed length. Visualize the resulting conduit before bending, perhaps while holding it in the proper orientation. Place one foot on the conduit and the other foot onto the bender foot.
A very important step in the bending process is to apply foot pressure, not just pull with your. Measure the length of conduit where you need the 90 to be and mark.
