Southwire Maxis MHB4000 (Hydraulic, 2-1/2 to 4): radius, deduct and gain
The Southwire Maxis MHB4000 (Hydraulic, 2-1/2 to 4) is a hydraulic bender for EMT, rigid (RMC), and IMC, 2-1/2" to 4". These are the numbers BendMate uses for each of its shoes.
Part numbers: MHB4000 (66978340); shoes MHB4000-250, -300, -350, -400
Specs by shoe
| Size | Centerline radius | Deduct | Gain | Notes |
|---|---|---|---|---|
| 2-1/2" EMT | 13 7/8" | 21 1/2" | 8 13/16" | Gain worked out from the radius. Deduct from the manual's Table 2; its special bending table agrees (21.49). |
| 3" EMT | 16 1/2" | 25 1/4" | 10 9/16" | Gain worked out from the radius. Deduct from the manual's Table 2. The manual's special bending table for this shoe implies 24.00 instead; check a test bend. |
| 3-1/2" EMT | 19 3/16" | 27 1/2" | 12 1/4" | Gain worked out from the radius. Deduct from the manual's Table 2; its special bending table implies 27.74. |
| 4" EMT | 21 1/2" | 30 1/2" | 13 3/4" | Gain worked out from the radius. Table 2 prints the deduct as '30-2/4'; its minimum stub length implies 30-3/4 and the special bending table 32.25. The EMT table header says radius 20.88, but the same shoe is 21.50 for IMC/rigid and the EMT table's numbers use 21.50. Check a test bend. |
| 2-1/2" RMC | 13 7/8" | 21 3/4" | 8 13/16" | Gain worked out from the radius. IMC/rigid pin hole. Deduct from the manual's Table 2; its special bending table implies 21.49. |
| 3" RMC | 16 1/2" | 24 1/4" | 10 9/16" | Gain worked out from the radius. IMC/rigid pin hole. Deduct from the manual's Table 2; its special bending table agrees (24.23). |
| 3-1/2" RMC | 19 3/16" | 27 1/2" | 12 1/4" | Gain worked out from the radius. IMC/rigid pin hole. Deduct from the manual's Table 2; its special bending table implies 28.18. |
| 4" RMC | 21 1/2" | 31 3/8" | 13 3/4" | Gain worked out from the radius. IMC/rigid pin hole. Deduct from the manual's Table 2; its special bending table implies 32.50. |
| 2-1/2" IMC | 13 7/8" | 21 3/4" | 8 13/16" | Gain worked out from the radius. IMC/rigid pin hole. Deduct from the manual's Table 2; its special bending table implies 21.49. |
| 3" IMC | 16 1/2" | 24 1/4" | 10 9/16" | Gain worked out from the radius. IMC/rigid pin hole. Deduct from the manual's Table 2; its special bending table agrees (24.23). |
| 3-1/2" IMC | 19 3/16" | 27 1/2" | 12 3/16" | Gain worked out from the radius. IMC/rigid pin hole. Deduct from the manual's Table 2; its special bending table implies 28.18. |
| 4" IMC | 21 1/2" | 31 3/8" | 13 11/16" | Gain worked out from the radius. IMC/rigid pin hole. Deduct from the manual's Table 2; its special bending table implies 32.50. |

Common questions
What is the deduct for 2-1/2" EMT on the Southwire Maxis MHB4000 (Hydraulic, 2-1/2 to 4)?
21 1/2". Subtract it from the stub length to find where to mark a 90. The shoe’s centerline radius is 13 7/8" and its back-of-90 gain is 8 13/16".
What is the deduct for 3" EMT on the Southwire Maxis MHB4000 (Hydraulic, 2-1/2 to 4)?
25 1/4". Subtract it from the stub length to find where to mark a 90. The shoe’s centerline radius is 16 1/2" and its back-of-90 gain is 10 9/16".
What is the deduct for 3-1/2" EMT on the Southwire Maxis MHB4000 (Hydraulic, 2-1/2 to 4)?
27 1/2". Subtract it from the stub length to find where to mark a 90. The shoe’s centerline radius is 19 3/16" and its back-of-90 gain is 12 1/4".
What is the deduct for 4" EMT on the Southwire Maxis MHB4000 (Hydraulic, 2-1/2 to 4)?
30 1/2". Subtract it from the stub length to find where to mark a 90. The shoe’s centerline radius is 21 1/2" and its back-of-90 gain is 13 3/4".
