Adjustable length with double-wall sleeve 500–850 mm

Adjustable length plus with double-wall sleeve 500-850mm

The original OSKAR Secure Adjust System connection technology (SAS-TEC) means that standard lengths cannot simply be shortened. The freely adjustable length with double-wall sleeve can be used as a wall pass-through and is specially configured: 

The component has a SAS-TEC connection on one side for installation at the appliance connection or T-piece. On the other side, the adjustable length has a double-wall sleeve for direct connection to the heating appliance's flue pipe.
