LADDER SAFETY / Glossary

Printer image
Whether you are selling, recommending or using a Bailey® ladder you will need to understand the most common terms. Some of these are standard, others are unique. Two common terms are outlined below to help get you started.

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.
