Bought a couple of these at the back end of last year after having the garage broken into and my bike stolen but have since moved and bikes are now in the house.
Have one in black and one in green. Also have a couple of heavy duty chains and locks, as per pics below.
Have both the mechanical fixings (so they can be moved) and chemical resin (so they can't!). Don't need them any more so fifty quid for a set, would ideally like to meet up/deliver in the Manchester/Leeds area due to the weight but can see what postage will be if needed.
