"I went to buy a cheaper 48" sash clamp but had a final check of the catalogue in-store. Unlike the website, there is a clamping capacity quoted and I realised that they were not long enough! Bought the Forge Steel clamp which has a 1200mm quoted capacity (Although, I found it a few mm shorter in practice). Very pleased with the last minute change. Strong, large capacity clamps which worked well and worth the extra money."
"Nice solid clamps - but be aware of the preserving grease/oil that is on the clamps. Clean this off before use as it gets on your work. Easy to use. screws work well, will buy some more soon as you can never have enough clamps!"
"these clamps are as good as most you can buy, and represent good value for money. I think they are superior to the wood or aluminum type, being made of steel and iron, and will serve the diy,er or light tradesman well, If i was using sash clamps all day i would go for record though,still number one but double the price"
"This is a recommended product, but only just. The clamps work fine, but mine we're covered in black grease and this took some cleaning off. Even when cleaned the clamps left grease marks everywhere. I now have black marks on my timber which will require sanding off. Spirits doesn't clean off all the marks. Only buy of you have plenty of time or don't mind the mess.
That aside the clamps are robust and work well. They are easy to operate, but then they are only clamps so how hard can it be. The only tricky part I found was when I wanted to add a spacer block in between the clamp and my wood to avoid clamp marks on the timber. Getting everything aligned and in place requires an extra hand so this bit can be fiddly.
On the whole not bad, but at 20 quid for a pretty basic bit of kit these are a little pricey."
"These cramps are reasonable strong and generally would work well.But they have one fault that lets them down. The floating shoes have a lot of play which means that they tilt back too far putting an upward pressure on the piece of work. I appreciate all these types of cramps do this a bit but on these it is excessive. You either have to compensate by using extra cramps on the other side or using shaped cramping blocks to compensate. I am going to return as they are not really good enough."
"Solid clamps but covered in oil.Unfortunately the supporting peg holes are full of oil and machining debris so unless you plan on jet washing the clamps first you're going to get caked in oil along with anything you're clamping. Returned to screwfix."
