Jackson Safety Contour Pipe Centering Head Tool, Curv-O-Mark Welding & Pipefitting Layout Tools, Size: Standard, J1879

Haven't yet used, but the bubble takes up most of the glassEdit gone back to tool and the liquid has completely gone from the glassEdit the liquid has completely gone, only used once

The media could not be loaded.  Returned 1st Curve o Mark I bought after hours of work. This was due to the spirit level leaking.Thought this was was a faulty item.Received 2nd one and was extremely careful while using it.The same thing happened as you can see in the video. The spirit level is now bone dry and useless.Waste of money.

This is a great little tool , I used it for marking out victaulic mechanical tees on 3” steel pipe today . Marked out my centre’s held it on the line hit it with a hammer and the holes were in identical positions . I bought the jumbo one too which seems nice. But I like this one because you can see were to place your punch and believe this one works better with smaller pipe

Brilliant little tool,takes the hastle out of arguing over if youre centre line is centre.Plonk it on, level it up hit the pin with a hammer jobs done,repeat further down the pipe get a straight edge and draw a line between the 2 punch holes. You are now the proud owner of a centre line on ye pipe with zero measuring and all by yourself no extra pair of hands required..Its built very well as you would expect and looks like it will last years.

Great product saves time on the job.

good quality product works well

Great tool as long as you calibrate it before use

Very good pice of kit from a professional fabricators point of view, only problem is the level on mine is not level, so to get a true reading I must slightly offset the spirit level
