Specs by shoe
| Size | Centerline radius | Deduct | Gain | Notes |
|---|---|---|---|---|
| 1/2" EMT | 4 1/4" | 7 5/8" | 2 1/2" | Gain worked out from the radius. Centerline radius from the GB bending guide; deduct from the manual, whose "bend radius" is the inside radius. |
| 3/4" EMT | 5 3/8" | 8 1/2" | 3 1/4" | Gain worked out from the radius. Centerline radius from the GB bending guide; deduct from the manual, whose "bend radius" is the inside radius. |
| 1" EMT | 6 1/2" | 10 3/8" | 3 15/16" | Gain worked out from the radius. Centerline radius from the GB bending guide; deduct from the manual, whose "bend radius" is the inside radius. |
| 1-1/4" EMT | 7 7/8" | 13" | 4 7/8" | Gain worked out from the radius. Centerline radius from the GB bending guide; deduct from the manual, whose "bend radius" is the inside radius. |
| 1-1/2" EMT | 8 3/8" | 13 1/2" | 5 5/16" | Gain worked out from the radius. Centerline radius from the GB bending guide; deduct from the manual, whose "bend radius" is the inside radius. |
| 2" EMT | 9 11/16" | 15 1/2" | 6 5/16" | Gain worked out from the radius. Centerline radius from the GB bending guide; deduct from the manual, whose "bend radius" is the inside radius. |
| 1/2" RMC | 4 3/8" | 7 3/4" | 2 11/16" | Gain worked out from the radius. Centerline radius from the GB bending guide; deduct from the manual, whose "bend radius" is the inside radius. |
| 3/4" RMC | 5 5/16" | 9" | 3 5/16" | Gain worked out from the radius. Centerline radius from the GB bending guide; deduct from the manual, whose "bend radius" is the inside radius. |
| 1" RMC | 6 1/4" | 10 1/8" | 4" | Gain worked out from the radius. Centerline radius from the GB bending guide; deduct from the manual, whose "bend radius" is the inside radius. |
| 1-1/4" RMC | 7 3/4" | 12 3/4" | 5" | Gain worked out from the radius. Centerline radius from the GB bending guide; deduct from the manual, whose "bend radius" is the inside radius. |
| 1-1/2" RMC | 8 1/4" | 13 1/2" | 5 7/16" | Gain worked out from the radius. Rigid and IMC share this groove. The guide prints 8-15/16 for rigid, which does not match its own inside radius; the IMC figure 8-7/32 is used. Deduct from the manual. |
| 2" RMC | 9 7/16" | 15 3/4" | 6 7/16" | Gain worked out from the radius. Centerline radius from the GB bending guide; deduct from the manual, whose "bend radius" is the inside radius. |
| 1/2" IMC | 4 3/8" | 7 3/4" | 2 11/16" | Gain worked out from the radius. Centerline radius from the GB bending guide; deduct from the manual, whose "bend radius" is the inside radius. |
| 3/4" IMC | 5 5/16" | 9" | 3 5/16" | Gain worked out from the radius. Centerline radius from the GB bending guide; deduct from the manual, whose "bend radius" is the inside radius. |
| 1" IMC | 6 1/4" | 10 1/8" | 3 15/16" | Gain worked out from the radius. Centerline radius from the GB bending guide; deduct from the manual, whose "bend radius" is the inside radius. |
| 1-1/4" IMC | 7 3/4" | 12 1/2" | 4 15/16" | Gain worked out from the radius. Centerline radius from the GB bending guide; deduct from the manual, whose "bend radius" is the inside radius. |
| 1-1/2" IMC | 8 1/4" | 13 1/2" | 5 7/16" | Gain worked out from the radius. Centerline radius from the GB bending guide; deduct from the manual, whose "bend radius" is the inside radius. |
| 2" IMC | 9 1/2" | 15 1/2" | 6 7/16" | Gain worked out from the radius. Centerline radius from the GB bending guide; deduct from the manual, whose "bend radius" is the inside radius. |

What is the deduct for 3/4" EMT on the Gardner Bender B2000 Cyclone (Large combo shoe)?
8 1/2". Subtract it from the stub length to find where to mark a 90. The shoe’s centerline radius is 5 3/8" and its back-of-90 gain is 3 1/4".
What is the deduct for 1" EMT on the Gardner Bender B2000 Cyclone (Large combo shoe)?
10 3/8". Subtract it from the stub length to find where to mark a 90. The shoe’s centerline radius is 6 1/2" and its back-of-90 gain is 3 15/16".
