Axministers eBay account are offering 1065mm long sash clamps @13.95 each. They are factory 2nds I bidder them down to 12 each and bought a couple to see what they were like. They came today one fault was the chain that holds the pin to the bottom part had opened and just needed closing. I cannot find fault with the other I'm trying to get half a dozen more.
