Available in a choice of lift-off or fixed pin variants the Load Pro range meets a broad range of high performance requirements. Where on-site removal of the door is necessary a choice of 5 hinge patterns can be supplied, each offering individual installation and performance characteristics. For more secure applications the 4815 fixed pin hinge with dual bearings is offered, with the option of radius corners for machine preparation or square corners for on-site installation.
Incorporating low-friction bearings to assist in the ease of door operation - Load Pro is the recommended choice for high efficiency specifications where conformity with the door opening resistance criteria of BS8300 and Approved Document M (Building Regulations) is paramount.

1. Determine the weight of the door including hardware
2. Make adjustment for use of door closer (Table. 1)
3. Make adjustment for width of door (Table. 2)
4. Calculate adjusted weight, select hinge (Table 3)

| 4710 | 10 | 60Kg |
| 4715 | 11 | 80Kg |
| 4717 | 12 | 100Kg |
| 4720 | 13 | 120Kg |

| 4815** | 12 / 13 | 100 kg / 120 kg |
| 4815R** | 12 / 13 | 100 kg / 120 kg |
Example.
Door weighing 55 kg, fitted with standard closer & 1100 mm wide
= 55 kg + 20% for closer + 18% for width = 55 kg +38% = 76 kg
Adjusted weight = 76 kg, use Grade 11 or above hinge.
Hinge location.
Doors ‘A’ & ‘B’ show hinge locations for maximum resistance to warping.
Doors ‘C’ & ‘D’ show hinge locations for maximum load carrying.
Tall doors. Door above 2.25m require 4 hinges as per Door ‘B’
