EN 604.2 safety adjustable levers like all the products of the Ergostyle® product family are renowned for their good style and also their ergonomical shape. The gently arched handle with a reinforced end of the lever gives the operator a good grip.
These safety adjustable levers are used where the inadvertent loosening or readjustment can result in accidents.
If not operated, the lever is not linked to the tapped insert, i.e. the adjustable lever turns freely.
As soon as the lever hub is pushed down, both serrations will engage, allowing the fixture to be released or clamped.
After "releasing", the connection disengages through spring tension.
