Specs by shoe
| Size | Centerline radius | Deduct | Gain | Notes |
|---|---|---|---|---|
| 1" EMT | 7" | 11 7/8" | 4 3/16" | Gain worked out from the radius. Radius from the Greenlee catalog; deduct and 90° limit from the 855GX manual. |
| 1-1/4" EMT | 8 1/4" | 14 3/8" | 5 1/16" | Centerline radius: Worked out from the manufacturer’s bend tables Gain worked out from the radius. Radius fitted from the 855GX manual's bending tables less Greenlee's 3% springback allowance. The catalog's 8-13/16 is larger than the 1-1/2 shoe's radius and doesn't fit the tables. |
