Resilient up to a maximum of 350 kg when the telescopic rod is fully retracted. Extremely stable construction due to highly durable steel pipes and non-slip PVC contact surfaces (9 x 7 cm). Single-handed operation thanks to 2-component plastic handle with pump mechanism. Quick-slide button for rapid extension and retraction of the telescopic bar. Controllable holding force by turning the support on the grip. Application also on slopes due to continuously swivelling contact surfaces from -45° to +45°.
