Fixing Clamps
 | Specially designed fixing clamps (deposited design) are used for the attachment of wall fasteners and safety cage hoops to the ladder uprights. These fixing clamps can be clipped to the ladder uprights at any desired position, which, together with the availability of a large range of wall fasteners, provides for fast and easy installation on most support structures. The ladder can be fitted parallel or perpendicular to the wall. The vertical distance between wall fasteners should not exceed 9’10” or 3 m, except when reinforced uprights are used. |
 |
 |  |  | The fixing clamps can be fitted in two ways: completely fixed, or allowing vertical movement. The fitting allowing vertical movement is used for long ladders, to allow for different thermal expansion of the ladder and the building structure. |
Ladder With Safety Cage
 | 1/2 cage |  |  | According to standard ISO 14122-4 (machinery access) a safety cage is required for ladders above 9’10” or 3 m (except when a lifeline is used, see page 3.7). The safety cage has to provide a free diameter of minimum 2’2” or 65 cm and maximum 2’7” or 80 cm. The JOMY safety cage is composed of 5 round cage uprights Ø 11/16” or 18 mm, which pass centrally through the hoops with square section of 1” or 25 mm. The free diameter within the hoops is 2’4” or 70 cm. The vertical distance between the hoops can be fixed freely according to required specifications. It is recommended to limit this vertical distance to maximum 3’3” or 1 m. |
