How to install straps on my FlowStop

For devices wider than two (2) meters, straps and carabiners are also provided.

The installation of straps and the attachment of fasteners to the ground are the sole responsibility of the Customer. Fasteners (dowels, screws, or any other equivalent accessories) are not provided by FlowStop.

Compatible surfaces

Flowstop works on most surfaces, whether your pictures are made of brick, stone, concrete or plaster, your FlowStop will fit perfectly thanks to its joint that can fill up to 1 cm of space or imperfection on your wall.

If your surface is too smooth, such as aluminum or painted wood, your FlowStop will slide upward instead of pressing downward.

In this case, it will be necessary to place a non-slip strip on each side, which we will provide with your order


Incompatible Surfaces

FlowStop cannot be installed on wooden cladding, nor on aluminum or PVC cladding that is too flexible, nor on plasterboard cladding.

Indeed, the pressure exerted by the FlowStop would be too great and could cause damage as well as improper installation of the device.
