I use a nail driving bar, its great for fixing gripper under radiators and around sanitaryware,and marble fireplaces. You place one end on the gripper nail and hit the centre with your hammer and hey presto the nail is driven home
very good tool, especiallly for getting under them low double radiators or under them round bay radiators where the radiator doesn't quite fite the bay.
i THOUGHT NAILS WERE MADE OF METAL.oH NEVER MIND!.I use the bolster cos by the time you have managed to get it from thew box the job is done (for me it is anyway).
