"Purchased two units to clamp the mortise and tenon joints on a window I was making. Wanted the cast iron clamps but needed them in a hurry and they were out of stock. "Made do" with these lighter clamp and they did the job well.
They were easy to position and tighten.
Good value for money and will get well used now that I have them!"
"Does exactly what you want it to do - but is so easy - massive length - good grip - great for doors or other large items. I bought 2 units - smart move especially when you need to ensure consistency..."
"This was so easy to use. So easy to slide open or close the jaws. Not sure on the plastic caps on the ends of the T Bar (the handle). These fall off very easily and could easyily be lost. Having said that, it does make it easy to remove the bar, if it gets in the way.
"lightweight clamps but more than up to heavyweight clamping tasks, you are never going to assemble regular household doors and windows with these but for the less demanding tasks like coffee tables and picture/mirror frames then these are a must buy. excellent all round"
"An excellent choice for the average diy enthusiast who only needs to use these on an occasional basis as they are a fraction of the cost of more robust clamps. They do the job perfectly adequately and should last well if used sensibly."
"These are certainly not the heavy weight Record sash clamps that you could keep under the bed for self defence. However, for light to medium clamping duties they are just fine. If you have a big clamping job on and need an armful of clamps then I doubt you can find them much cheaper."
"Stable and well made product. Obviously with softer aluminium u-rail you have to be careful not to force the clamp in the wrong position or can dig in and dent. Good for lightweight clamping applications."
"Well, they do what they say on the tin. Pretty well constructed, a little bit of play until you really tighten the clamp. Light weight, so not too hard to move around. I used on a 2m x .8m x .3m bookshelf being glued-up. Worked fine."
"I bought these because I needed 3 quite long clamps and they were much cheaper than steel ones. They might be OK for very light weight projects which is why I didn't give them zero stars, but for my purpose they were completely inadequate and went wrong in multiple ways. Probably my own stupid fault for going cheap."
"These are extremely lightweight and should not be sold as sash clamps.
Sure, they look like sash clamps but they're not and are only useful as 'say' a second set of hands to just hold something in place or, you like making four foot windows, out of lightweight beading for, an extremely large dolls house.
Screwfix shouldn't be selling them or if they do, rename them and explain what they're useful for (possibly, lightweight model making at best?)"
"I've used them a couple of times now and the floating end doesn't always lock, the clamp end pitches on the shaft and gets stuck, and any thing over low pressure results in the clamp twisting and deforming. I bought the 24" & 48" and wouldn't consider purchasing any more of them."
"i have about 24 of these type of clamps in different sizes, but the last 4 -48 inch ones i bought are total rubbish.when screw in or out the head keeps jamming,impossible to work with unless youve got 3 hands,i think they are a cheaper version of the original type ,but not in price. i will be taking them back"
