			'''Box Folders''', or '''Box and Pan''' folders differ in that the clamping plate is made up of several different width sections which can be arranged to enable folds within the limitations imposed by the width of boxes or trays to be folded.

			<span style="color: green">'''Note:'''
			When folding sheet metal which has been marked out using a '''[[Scriber]]''', always ensure the scribed line is on the inside of the fold. In this way, the scribed line will close up because of '''[[Compression]]''' whereas, if on the outside of the fold, the resulting '''[[Tension\|Tensile]]''' forces could open it up and even cause the metal to tear or start to fracture - especially if it is then subjected to vibration. For this reason, scribed lines must not be used at all to mark out fold lines in aluminium for aircraft manufacture.

=====Description=====

Commercially available '''Folding Bars''' are a single piece construction formed by bending a length of [https://en.wikipedia.org/wiki/Carbon_steel#Mild_steel '''Mild Steel''']''' bar as shown.

The design enables the bars naturally to spring together and grip a piece of sheet metal prior to being placed in a '''[[Engineers Vice|Vice]]''' to hold the sheet firmly for bending.

Additional force can be applied by '''[[G Cramp|G Cramps]]''' or '''[[Hand Vice|Hand Vices]]''', if needed on longer folds for example.

'''Folding Bars''' can readily be self-made using strips of steel bar or angle section which are then gripped together in a '''[[Engineers Vice|Vice]]'''.

They are more convenient to use if they are located against each other with '''[[Nuts, Bolts and Washers|Bolts and Wing Nuts]]''' as shown.
