Delivers reliable panel attachment through an intuitive quarter-turn motion with positive locking engagement.

Side lever actuation provides convenient connections when vertical space is limited

The PFQTL™ panel fastener addresses the limitations of traditional slide plungers by preventing accidental unlocking during vibration or mis-operation, providing superior reliability in demanding applications. The quarter-turn mechanism provides superior holding strength of the pin in the extended position compared to spring loaded designs while maintaining the convenience of toolfree operation, combining security with ease of use.

The positive engagement system of the PFQTL™ fastener gives operators confidence in secure attachment and reduces the risk of panel displacement during equipment operation – ensuring consistent performance throughout the service cycle.
