Four-Point Saddle Calculator

Calculate four-point saddle marks from measured length, straight section, and the Z, L1, and L2 values for your bender.

Enter the value for a bender table that uses this same four-point mark layout.

Use the L1 value from the same bender table and setup as Z and L2.

Starting values are for a Greenlee 555DX-22 with 1/2 in. EMT, 45° bends, and a 6 in. obstruction. Replace with values from a table using this mark layout.

Follow the reference used by the written step or diagram for your exact bender.

Use the same bend sequence, table row, and Mark 3 reference used to determine Z, L1, and L2.

Geometry aid onlyDisplayed marks are rounded to the nearest 1/16 in. Confirm take-up, multipliers, bend radius, and mark-pointer alignment for your conduit and bender. Make a test bend and verify the finished dimensions.

Method and field check

The entered Z, L1, and L2 values must come from the matching bender table, conduit size, and bend setup. Select the Mark 3 reference convention used by that instruction and verify the mark sequence before bending.
