- There was no resisting
force to prevent the legs of the ladder from slipping out sideways.
Rubber feet attached to the ladder legs will help the legs to stay in
place. More friction will be created between the rubber and the ground
as opposed to the wood and the ground.
- There was no connection
between the legs of the ladder to prevent them from moving apart and
eventually collapsing flat. The steel chain, connected to each leg will
prevent the legs from separating too far.
- There was no stop
on the hinge at the top of the ladder to prevent it opening wide. The
stop locks the hinge into place.
