STRAIGHTENING OF BARS

The straightening of the steel reinforcement bars should be approached with care and consideration to using
the correct technique. We recommend the use of our Rebox Bar Bender (refer below photos). We do not
®
recommend the use of steel pipes, tubes or other implements that are not at the correct diameters, due to
when straightening of the bar, they can cause kinks or could apply incorrect re-bending forces.

Rebox Bar Bender is a straight tube pipe that has a slightly larger internal diameter than the outer diameter
®
of the steel reinforcement bar ribs that it is being placed over to straighten. One end of the tube is cut on an
angle to aid in supporting the outside edge of the reinforcement during bending and also allows for a smooth
continuous travel during straightening.
When first installing the Rebox Bar Bender, the tool should be pushed onto the end of the lap reinforcement
®
bar to be straightened, and as far along as possible, to the full length of the bar to where the bend radius is.
Once inserted, the bar needs to be straightened in a continuous motion and as the bar straightens, the tool
needs to be continually pushed (slid) along the bar towards the metal back cover of the box, and should end
up touching the cover upon completion of the straightening.

The tool is then removed and the straightened steel reinforcement bar checked for alignment and length for
lapping/connecting to the subsequent main reinforcement. All other bars are then straightened according to
the same procedure.
Rebox Bar Bender is available in the following sizes:
®
RBB-10 to suit 10mm diameter bar.
RBB-12 to suit 12mm diameter bar.
RBB-13 to suit 13mm diameter bar.
RBB-16 to suit 16mm diameter bar.

Length of Rebox Bar Bender suits most lap length bar requirements but special lengths are available upon
®
request.
The tool is painted orange, comes with a comfortable hand grip on one end and is clearly marked so it can be
checked for its appropriate size and use with the steel reinforcement bar diameter that is to be straightened.
