The company of bending conduit isn't so complex because it seems at the start making bends that healthy correct the 1st time is straightforward if one follows a number of easy principles. because the writer promised, no longer a unmarried technical observe has seemed during this handbook -no excessive math... no “trig”...no sines...no co-sines...no algebra or geometry used to be had to examine the straightforward paintings of creating conduit bends that healthy!

Make a test 90° bend. Step 2 Use a T-square to be certain the test bend is a true ninety (90°). Step 3 Measure the distance from the floor surface to the pencil mark on the conduit. make a note of it. Step 5 At some visible point, file a “notch-mark” on the sector. This distance is your “take-up” symbol for future 90° stubs. (To avoid fractions, this mark should be placed on the even inch). Making offsets and saddles Most ratchet benders have a degree-of-angle indicator. If no degree scale, use a protractor to check angle of bends.

Slide a pipe sleeve over the stub (as shown in Fig. the closer the better. This forces the conduit to bend in the groove until it is worked into the desired position. ” This is done by the use of a threaded IPS nipple long enough for threads to clear the collar of the bender. To this nipple they attach a plumber’s 90° short elbow and screw a conventional bender handle into the elbow. This assembly gives the operator a handy means of holding the bender head steady and firm as he forces the conduit (using the pipe sleeve) to bend in the bender groove until it FIG.

A bent handle that works loose is actually unsafe. If a threaded handle backs off as little as one quarter turn during the fabrication of a bend the operator could be thrown off balance, lose his footing and fall. A field made handle using scrap electrical conduit is false economy. Not only does the practice entail excessive labor costs but benders with easy bending handles soon become a counterproductive liability. A handle that stays straight is a real “plus value” on the job because most hand benders are engineered so that a straight up (vertical to the floor) handle indicates a 30° bend has been made in the conduit.
