"I bought two of these, plus two 36" ones, to put back together some flat pack drawers that had fallen apart. Very good clamping action for the work I needed, so just the right quality for me. If I was doing some really heavy duty clamping then I suspect that the rather basic mechanism (and plastic parts) would not stand up to too much pressure. On one of the 4 sash clamps I got the screw action of the clamp was rather stiff, and oil didn't make a difference. I managed Ok though. As previously mentioned the collar that slides along the rail can catch occasionally, but just keeping it straight as you adjust the coarse length is sufficient. So - professionals stay away but for DIYers these work great."
"I'm using these sash clamps to hold two planks biscuited side to side and they work perfectly. My only complaint is that the small rods used as levers to screw the clamps are only secured by rubber end caps that keep coming off. Would have been better if the rods were crimped to stop them falling out. I would recommend this product."
"A brilliant piece of kit for any one i`m not a professional but this did the job perfectly. The price was very cheap compared with the diy stores. i was very pleased with it. it has a ratchet so you can close it as as small as you need or as long as the bar will allow. I would recomend this to any one looking for one of these."
"Good value lightweight 24 inch clamp. Handy for the decking project. Handled the 6x2 clamping with ease. Only criticism would be the length of jaw which at 40mm has its limits for stability. Good buy."
"I brought this as I have taken on the task of building some photography props out of wood and these seem good value for money. 3 star rating for overall rating as there was a piece of rubber of the handle that stops the bar from coming out the clamp adjuster."
"You get what you pay for. They work well in a domestic environment but I wouldn't reckon they would last on site. The plastic bits fall off the handles and need to be superglued straightaway. Lightweight manufacture. Pay more if you want longevity."
"A cheap useful tool that just about does the job. The clamp looks like it won't last long but I've only had it a month so we'll see. I've used them to make a planter and a table frame so far. I'm saving for the expensive ones."
"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."
"These are very cheap which is why I got them; however they have a couple of faults. The plastic caps fall off the handles which makes the handles fall out of the shafts. They also run poorly and get stuck frequently; I took one back which barely worked out of the box, and after a little light duty the other two were running badly too. Taken back for a refund - top marks to Screwfix for easy returns process."
"Very badly made product, the ratchet locking end is ok, but the t-handle adjustable end is awful, it jams up when you turn the handle, it only slides if you pull it with your hand too. Will be taking them back"
