I just had a new carpet laid and was told that the door would have to come off as between the carpet and underlay the door would need about an inch taken off the bottom. I decided the best way would be to clamp a straight edge across the bottom to use as a guide for the saw. No clamps, so on line I go and found these great little clamps at a really good price they arrived next day half an hour later the door was an inch shorter and hung back on the wall. I went to register the clamps and had a look at what else Silverline supply and now I have bought, used and registered several Silverline tools and I believe that you will find it hard to find better quality tools at such a reasonable prices as those produced by Silverline. anytime I need a tool for a DIY job I will go straight to silverline for it.
