This is another useful application for our tube clamp Bolt-ons. Using a pair of 42mm vertical tube clamps, this guide will show you how to seal off gaps in temporary fencing by terminating the final panel against a shipping container so that nobody can break through by moving the end of the last panel out of its block.
Some background info about fence panels
Temporary steel mesh fencing, often called heras fencing (and with any multitude of misspellings; Harris, herris, etc) after one of the leading player in the industry, are modular tube framed, wire mesh fence panels which can be quickly erected to create temporary secure areas at events, workplaces and construction sites. The outside tube of the frame is typically around 38mm diameter, and using simple double tube clips like the one pictured below, are joined one after the other to create a fence to the length required. With the ability to place each panel at an angle, this makes for an enormously versatile and practical short term fencing solution.
Weak points in mobile fencing
However, while separating two fence panels to create a gap to pass through requires undoing two of these fence clips with a spanner, anyone trying to pass by one of these fences will look immediately to the final panel in the run, which may be attached to nothing at all, and can simple move it out of the way by lifting it out of its block.
Solving the problem with Domino Clamps
In circumstances where these fence panels might be able to terminate next to a shipping container or some other containerised unit, such as a containerised generator, you can easily create a solid mounting point that the final fence panel can clip to and close off the gap.
Three different sizes of palm railing style clamp in our shop allow you to clamp a vertical steel or aluminium tube vertically up the side of a container. In this case, the 38mm tube of the fence panels is exactly halfway between two sizes of tube clamp; 42mm and 34mm diameter. We have tried with both, and find that the fence panel clips work better with the larger size of 42mm tube.
InstructionsYou will need:
- 2x Domino Clamps
- 2x 42mm vertical tube clamp fittings.* (at least one of these needs to be NOT BORED THROUGH)
- 4x M12 x 25mm bolts *
- 4x M12 Washers *
- Minimum 2.5m length of 42mm Steel tube.
Pick any two holes on the shipping container, one directly above the other and secure a Domino Clamp in each one. For anyone totally new to Domino Clamps, you can see full and detailed instructions on how to do that in this installation guide here
The tube clamps will bolt straight onto the Domino Clamp with the bolts provided, so this can be done on first on the bottom one, and then on the top. If the top tube clamp is not bored through, then this one will need to go upside down, and you’ll need to make sure your tube is cut exactly the right size.
If your top clamp is bored through, please follow our easy step by step video on how to install long scaffolding poles safely with just one person.
Once the vertical tube is in place, make sure all the bolts and grub screws are done up tight, and now you have a secure pole to clip the tube of your fence panel onto using your normal clips.
Please let us know in the comments how this works for you, and if you come across any brands of fence panelling that perhaps use different size tubing, and we will keep this page up to date with such information.
Needless to say, this bar could have multiple other uses, and the same method can be used to attach a vertical 48mm tube or a vertical 34mm tube.
