1. Enhanced structural rigidity. 

2. Increased internal width for cables. 

3. High performance coupling. 

4. Safety edge. 

Slotted Side Section: 

1. Allows faster installation as the ladder can be cut to any length and coupled without on-site drilling. 

2. Fixing to ladder sides. 

3. Reduced weight. 

Shallow Channel Rungs: 

1. The welding of the rungs to the lowest point of the side section ensures maximum loading height. 

2. High strength even in the widest ladders. 

3. Compatible with every known type of cleat, tie and bonding with infinite adjustment. 

4. Rungs alternately inverted (on lengths) permitting suspension of light fittings etc.from underside.
