90° Stub-Up Bend:
The stub bend is made by bending a piece of conduit into an L shape or 90° bend by placing the free end
(short end) of the tube to a predetermined length as indicated in the diagram below. This is the most
common bend and is a building block for other bends. Common uses for this bend are: Running conduit
into electrical boxes, running conduit up or down walls, running conduit into walls through floors and
ceilings and making inner and outer corner turns.
1.
Determine the overall free end height of the conduit you want after the bend.
2.
From the overall free height, subtract the stub height listed in the Bender Take-Up Table for the
conduit size you are bending.
Klein Tools has provided the correct stub height on each bender head.
3.
On the conduit, measure from the free end to be bent up the calculated number and mark the
conduit.
As an example, to bend 3/4” EMT conduit have a free end height
of 8.5”, the table indicates to subtract 6” from the 8.5” which
leave 2.5” from the end to bend up to make the mark.
Tip:
Advanced benders can lay a tape measure next to the conduit and perform the
bending operations if the bend does not call for high degree of accuracy.
4.
Always use the proper size conduit bender for the conduit size being
bent. The conduit will not bend properly and/or will be damaged if a
mismatch of bender and conduit size is used. Place the bender onto the
tubing with the hook pointed towards the free end to be bent upwards.
Make sure the conduit is resting properly in the bender’s hook and
lineup the arrow symbol with the mark you placed on the tubing.
