Die set 100 is designed for forming acute angle offsets on 18 gauge and lighter material. Set 101 is used for air forming open angle offset. Set 102 is for bottom bending shallow open angle offsets in material up to 16 gauge in thickness. Die set 103 will air form a 90° when available tonnage eliminates considering bottom forming dies.
Die sets 104 and 105 are used for forming material thickness offsets close to the end of the sheet. Die set 106 is required when the flanges are shorter than the offset being formed; gaugeing is built into the set to ensure consistent and accurate parts
