Frictioned gas springs Free Stop
The Free Stop gas spring has the same build as standard gas springs. The main difference involves the piston, especially designed to make the rod go in and out with some friction.
The friction between piston and body will prevent the spring (and therefore the door) from opening to the full automatically, so that the user can open and close the door gradually and stop it in any position. Body and rod have end fittings that allow to fix them.
The use of a Free Stop gas spring is especially indicated on wall cabinets installed high above floor, so that the doors will not be hard to reach, once they are lifted.
With a Free Stop gas spring you can stop the door in a more comfortable position and control the extent of door opening.
