PUNCHLOCK
A method of connecting the tread to the stile of a Bailey® ladder.
Benefit: Provides greater torsional rigidity. Torsion is the stress/deformation caused when one end of an object is twisted in one direction and the other end is held motionless or twisted in the other/opposite direction. The Punchlock® design helps prevent this ensuring a ‘super strong’ tread to stile joint is achieved, hence making the ladder more rigid and stable to use.
Key Benefits:
• Creates a very tight and strong tread to stile joint
• Greater torsional rigidity
• Makes the ladder safer to use
QUICKLOCK
A patented design for internal spreader arms.
Benefit: Provides additional stability for the ladder by ensuring that when engaged/open, the chances of the ladder ‘walking’ or moving from side to side are reduced. This is a great test when buying a ladder. Simply open the ladder and push on one or more corners. If the ladder moves in a forward motion then there may be an increased chance that this will occur when the ladder is actually used.
Key Benefits:
• Reduces ladder-walk
• Increases stability and safety
• Is easy to use and won’t catch/trap fingers
