The Indalex, Gorilla and The Warehouse ladders “struggled” to meet some of the individual tests – and this reduced their overall stability/strength ratings.
We also tested the feet of the front and rear legs for friction and grip against the floor. The Ox OXSE06 was significantly better than the others – it gave a secure grip.
Ease of use
Folding and unfolding
The Ox OXSE06 had the most useful setup, with a tray located between the spreaders for holding tools or paint containers.
The Alco, Bailey, The Warehouse and Warrior all had a spreader bar on each side of the ladder, making them relatively easy to fit and release.
The Rhino and Gorilla had cross-braced spreaders. The Gorilla spreaders worked well, but those of the Rhino were slightly out of alignment and hit the inside of the rear leg. We also had to file one of its spreader slots to make it wider, so that it would fit the locating lug.
The Indalex's X-shaped cross-brace worked well enough in our test.
Opening out straight
All the ladders used latches to secure the ladder in the opened-out-straight position. The catches of the Alco, The Warehouse and the Warrior worked well without problems.
But not all worked well. One catch on the Rhino required a judicious hammer blow before it disengaged. The Bailey, Indalex, Ox and Rhino all had stiff-to-operate catches. The catches on the Gorilla appeared to have been bent in transit and had to be reshaped to make them work.
We also assessed how secure the ladders felt while standing on the fourth step and shifting our weight about. The Bailey, Ox and Warrior felt the most secure. We felt least secure on the Rhino and The Warehouse.
