Default Scaffolding with pipe system clamps....

I was fortunate to find about 40 of these clamps at a local scrap yard Friday afternoon while I was picking up some square tubing for the FELs being fab'd.

I have used them in the past and they will surely make things easier for me to have 'break down' scaffolds for use around the place. I've always wanted a towable scaffold or a motor driven steerable scaffold system for gutters and access to getting on a roof. Things will be considerably easier to make that happen now.

These things are heavy and well made with little rust or age to show. The guy at the yard said he was tired of having to pick them up and keep them in one pile. I figured for a buck per, it was a good deal considering prices range from $15 to $30 depending where you get them.

How do these:
1. Clamp a cross bar ?
2. Keep from sliding down ?

I see these similar, but only overseas.

Many years ago we did a lot of work for a company that did staging work for large concerts and outdoor events. They used a variety of components depending on what they were doing but the "Cuplock" system was by far the most commonly used. We assembled thousands of feet of posts and connecter bars during that time. As far as I know the Cuplock system originated in Europe but, since it was far superior to most of the domestically available stuff at the time, it was very popular with the staging companies...

You do not use the typical cross bars found with typical scaffolding. These are used for pipe that fits within the clamps pinching ability.

Believe me, there is enough force with the sized threads and nuts to deform the pipe being clamped if you get forceful.

Once in place it takes a sledge to get any movement out of them while installed.

I was happy to bring these home as they will work on open ended piping of correct size and with a tad of side wall integrity.

My auld lad would be very jealous. He has a bunch of H frames and pipe and a sack of those clamps but never enough clamps it seems.

Rarely used in the trades in Ireland today, only for cross bracing but still weirdly popular in the UK.

99% of scaffolding used here is kwikstage, only tool needed is a hammer.

I wanted the ease of take down and build up as storage under roof here is at a bit premium and I'm out of room.


It was with high hopes after the Step danger died, that I'd have all this extra room out at the farm and buildings.


What I quickly realized was that the only thing he added to the place was a Zero Turn mower, that I had paid half for. Everything else he used was mine. sigh. You guys have no idea the cussing I've done finding my rusty tools out and about where he last used them and walked away.


I'm pleased as punch to now have many extra of these clamps for that type of scaffolding and work. Will make things easy for an old guy.


Over the years I've pulled up and removed several hundred feet of chain link galvanized fencing for neighbors as back in the day, that was the fencing to have. Now I've got several hundred feet of the top piping and another several hundred feet of 6' and 10' pieces of 1 1/2" and 2" gal piping that is the same wall thickness as what we use for scaffolding at work. So, the expense now is nil for my scaffold needs.

Default coupler

these are called 'swivel couplers" used to couple two sections of 2"OD steel pipe at an angle with the capability of swiveling to accommodate any angle. Some of these couplers are rigid 90deg angle as well,without the swivel in the middle. You can also get 1/2couplers that have the one pipe clamp provision and a hole in the middle of the body so you can insert a 1/2" bolt thru the hole and bolt objects to the coupler..its a very strong connection when assembled properly
