STUB-UP BENDING INFORMATION AND CHARTS

— continued

To locate bending marks and springback of 15, 30, 45, 60, and 90 degree

bends for a desired stub:
1. Check Chart A, B, C or C1 on Page 21 for deduct length. Note that minimum

stub length is deduct length plus 2".
2. Measure and mark desired stub length on conduit ( stub length mark ).

Subtract “Deduct Length" from this mark and make a second mark

( bending mark ). See Fig 20a and 20b. Place bending mark at front edge

of shoe hook. See Figure 20c. Check Chart A, B, C or C1 on Page 21 for

springback of desired degree of bend. Bender should be advanced to this

degree to obtain desired degree of bend.
