TLX.Z-A

Toggle latches

Zinc-plated steel. Without locking spring cotter pins.

Features and applications

TLX hook clamps have got an internal spring mechanism that maintains both the control lever and the locking hook in the open position, allowing an easy operation.

Once the dead center has been overcome, the elasticity of the sheet metal parts causes the locking of the clamp.

For a correct functioning of the hook clamp, it is necessary to keep the hole centre distance f, by means of low flat head screws or rivets.

The TLX-B version allows the prevention of the accidental opening of the closure by means of a spring cotter pin inserted into the d₁ hole.

The maximum load values indicated in the table are the result of laboratory tests obtained in a state of static stress. Such values have to be considered as purely indicative and must be verified under the specific conditions of use.

Fig.1: in the unlocked position, the hook clamp is held in the position indicated by two internal torsion springs.

Fig.2: by lifting the lever, the locking hook is moved towards the stop.

Fig.3: by pressing the lever, the locking hook engages with the stop until it reaches the locking position.

Fig.4: to unlock, simply lift the locking lever.

All these engaging and disengaging operations of the hook clamp can be done by using one hand only, since in its movement the locking hook follows the lever.
