Hi,
I have a 'Laddermate', (H&S approved) ladder safety device for sale in very good condition as its had hardly any use!
Its manufactured from very robust galvanized solid steel and adjusts width-ways to suit just about any ladder size.
BRILLIANT PRODUCT, A REAL LIFE SAVER, open to any sensible offers.
I live in Cambridge, contact me on: 07968 050 007.
Cheers,
Skippy
