What it is
Extension for cleaning brush BS M8 420 mm Fischer 508791. Key specifications: type BS chimney brush extension, length (mm) 420, pack (pcs) 1.
The extension is a rod or tube that lengthens a tool or accessory to reach the bottom of a deep hole; the adapter is a fitting that allows parts with different connections to be joined.
What it is for
Used for chemical anchoring, where the load or edge distance rules out a mechanical anchor and for structural fixings, where the fixing is load-bearing and must be calculated.
How to use it
Fit or screw it in fully, with no play, before starting work. Check that the connection is compatible with the tool and with the accessory to be connected. The connection should be rechecked if working for a long time, because vibration can loosen it.
