The all-new Ceilingboard Hanger allows just ONE PERSON to fit FULL-SIZE plasterboards to ceilings. The Ceilingboard Hanger removes the need for large plasterboard hoists and lifts, and takes all the hard work out of putting a FULL 2400mm x 1200mm 12.5mm sheet of plasterboard, weighing 25KG up on the ceiling joists ready for fixing. This usually difficult and labour-intensive job can now be completed by just ONE PERSON, saving you both time and money – and when you’re done, simply store it away in your toolbox!
