Spring Assisted Covers

Where ease and speed of opening is of prime importance, hinged units can be provided with gas struts or torsion springs which as standard are installed to partly lift the cover.  Complete opening of the cover and it's closure is then accomplished under hand pressure.


The pressure and type of gas struts/number of torsion springs used can be varied to fully open the cover automatically, when the locking mechanism has been deactivated, requiring no hand pressure.  The gas struts can be adjusted on site if necessary.


All hinged units incorporate a hinge safety stay to secure the cover in the open position.
